-/**
- * struct dev_pm_ops - device PM callbacks
- *
- * Several driver power state transitions are externally visible, affecting
- * the state of pending I/O queues and (for drivers that touch hardware)
- * interrupts, wakeups, DMA, and other hardware state. There may also be
- * internal transitions to various low power modes, which are transparent
- * to the rest of the driver stack (such as a driver that's ON gating off
- * clocks which are not in active use).
- *
- * The externally visible transitions are handled with the help of the following
- * callbacks included in this structure:
- *
- * @prepare: Prepare the device for the upcoming transition, but do NOT change
- * its hardware state. Prevent new children of the device from being
- * registered after @prepare() returns (the driver's subsystem and
- * generally the rest of the kernel is supposed to prevent new calls to the
- * probe method from being made too once @prepare() has succeeded). If
- * @prepare() detects a situation it cannot handle (e.g. registration of a
- * child already in progress), it may return -EAGAIN, so that the PM core
- * can execute it once again (e.g. after the new child has been registered)
- * to recover from the race condition. This method is executed for all
- * kinds of suspend transitions and is followed by one of the suspend
- * callbacks: @suspend(), @freeze(), or @poweroff().
- * The PM core executes @prepare() for all devices before starting to
- * execute suspend callbacks for any of them, so drivers may assume all of
- * the other devices to be present and functional while @prepare() is being
- * executed. In particular, it is safe to make GFP_KERNEL memory
- * allocations from within @prepare(). However, drivers may NOT assume
- * anything about the availability of the user space at that time and it
- * is not correct to request firmware from within @prepare() (it's too
- * late to do that). [To work around this limitation, drivers may
- * register suspend and hibernation notifiers that are executed before the
- * freezing of tasks.]
- *
- * @complete: Undo the changes made by @prepare(). This method is executed for
- * all kinds of resume transitions, following one of the resume callbacks:
- * @resume(), @thaw(), @restore(). Also called if the state transition
- * fails before the driver's suspend callback (@suspend(), @freeze(),
- * @poweroff()) can be executed (e.g. if the suspend callback fails for one
- * of the other devices that the PM core has unsuccessfully attempted to
- * suspend earlier).
- * The PM core executes @complete() after it has executed the appropriate
- * resume callback for all devices.
- *
- * @suspend: Executed before putting the system into a sleep state in which the
- * contents of main memory are preserved. Quiesce the device, put it into
- * a low power state appropriate for the upcoming system state (such as
- * PCI_D3hot), and enable wakeup events as appropriate.
- *
- * @resume: Executed after waking the system up from a sleep state in which the
- * contents of main memory were preserved. Put the device into the
- * appropriate state, according to the information saved in memory by the
- * preceding @suspend(). The driver starts working again, responding to
- * hardware events and software requests. The hardware may have gone
- * through a power-off reset, or it may have maintained state from the
- * previous suspend() which the driver may rely on while resuming. On most
- * platforms, there are no restrictions on availability of resources like
- * clocks during @resume().
- *
- * @freeze: Hibernation-specific, executed before creating a hibernation image.
- * Quiesce operations so that a consistent image can be created, but do NOT
- * otherwise put the device into a low power device state and do NOT emit
- * system wakeup events. Save in main memory the device settings to be
- * used by @restore() during the subsequent resume from hibernation or by
- * the subsequent @thaw(), if the creation of the image or the restoration
- * of main memory contents from it fails.
- *
- * @thaw: Hibernation-specific, executed after creating a hibernation image OR
- * if the creation of the image fails. Also executed after a failing
- * attempt to restore the contents of main memory from such an image.
- * Undo the changes made by the preceding @freeze(), so the device can be
- * operated in the same way as immediately before the call to @freeze().
- *
- * @poweroff: Hibernation-specific, executed after saving a hibernation image.
- * Quiesce the device, put it into a low power state appropriate for the
- * upcoming system state (such as PCI_D3hot), and enable wakeup events as
- * appropriate.
- *
- * @restore: Hibernation-specific, executed after restoring the contents of main
- * memory from a hibernation image. Driver starts working again,
- * responding to hardware events and software requests. Drivers may NOT
- * make ANY assumptions about the hardware state right prior to @restore().
- * On most platforms, there are no restrictions on availability of
- * resources like clocks during @restore().
- *
- * @suspend_noirq: Complete the operations of ->suspend() by carrying out any
- * actions required for suspending the device that need interrupts to be
- * disabled
- *
- * @resume_noirq: Prepare for the execution of ->resume() by carrying out any
- * actions required for resuming the device that need interrupts to be
- * disabled
- *
- * @freeze_noirq: Complete the operations of ->freeze() by carrying out any
- * actions required for freezing the device that need interrupts to be
- * disabled
- *
- * @thaw_noirq: Prepare for the execution of ->thaw() by carrying out any
- * actions required for thawing the device that need interrupts to be
- * disabled
- *
- * @poweroff_noirq: Complete the operations of ->poweroff() by carrying out any
- * actions required for handling the device that need interrupts to be
- * disabled
- *
- * @restore_noirq: Prepare for the execution of ->restore() by carrying out any
- * actions required for restoring the operations of the device that need
- * interrupts to be disabled
- *
- * All of the above callbacks, except for @complete(), return error codes.
- * However, the error codes returned by the resume operations, @resume(),
- * @thaw(), @restore(), @resume_noirq(), @thaw_noirq(), and @restore_noirq() do
- * not cause the PM core to abort the resume transition during which they are
- * returned. The error codes returned in that cases are only printed by the PM
- * core to the system logs for debugging purposes. Still, it is recommended
- * that drivers only return error codes from their resume methods in case of an
- * unrecoverable failure (i.e. when the device being handled refuses to resume
- * and becomes unusable) to allow us to modify the PM core in the future, so
- * that it can avoid attempting to handle devices that failed to resume and
- * their children.
- *
- * It is allowed to unregister devices while the above callbacks are being
- * executed. However, it is not allowed to unregister a device from within any
- * of its own callbacks.

- * @num_altsetting: number of altsettings defined.
- * @intf_assoc: interface association descriptor
- * @minor: the minor number assigned to this interface, if this
- * interface is bound to a driver that uses the USB major number.
- * If this interface does not use the USB major, this field should
- * be unused. The driver should set this value in the probe()
- * function of the driver, after it has been assigned a minor
- * number from the USB core by calling usb_register_dev().
- * @condition: binding state of the interface: not bound, binding
- * (in probe()), bound to a driver, or unbinding (in disconnect())
- * @sysfs_files_created: sysfs attributes exist
- * @ep_devs_created: endpoint child pseudo-devices exist
- * @unregistering: flag set when the interface is being unregistered
- * @needs_remote_wakeup: flag set when the driver requires remote-wakeup
- * capability during autosuspend.
- * @needs_altsetting0: flag set when a set-interface request for altsetting 0
- * has been deferred.
- * @needs_binding: flag set when the driver should be re-probed or unbound
- * following a reset or suspend operation it doesn't support.
- * @dev: driver model's view of this device
- * @usb_dev: if an interface is bound to the USB major, this will point
- * to the sysfs representation for that device.
- * @pm_usage_cnt: PM usage counter for this interface
- * @reset_ws: Used for scheduling resets from atomic context.
- * @reset_running: set to 1 if the interface is currently running a
- * queued reset so that usb_cancel_queued_reset() doesn't try to
- * remove from the workqueue when running inside the worker
- * thread. See __usb_queue_reset_device().
- *
- * USB device drivers attach to interfaces on a physical device. Each
- * interface encapsulates a single high level function, such as feeding
- * an audio stream to a speaker or reporting a change in a volume control.
- * Many USB devices only have one interface. The protocol used to talk to
- * an interface's endpoints can be defined in a usb "class" specification,
- * or by a product's vendor. The (default) control endpoint is part of
- * every interface, but is never listed among the interface's descriptors.
- *
- * The driver that is bound to the interface can use standard driver model
- * calls such as dev_get_drvdata() on the dev member of this structure.
- *
- * Each interface may have alternate settings. The initial configuration
- * of a device sets altsetting 0, but the device driver can change
- * that setting using usb_set_interface(). Alternate settings are often
- * used to control the use of periodic endpoints, such as by having
- * different endpoints use different amounts of reserved USB bandwidth.
- * All standards-conformant USB devices that use isochronous endpoints
- * will use them in non-default settings.
- *
- * The USB specification says that alternate setting numbers must run from
- * 0 to one less than the total number of alternate settings. But some
- * devices manage to mess this up, and the structures aren't necessarily
- * stored in numerical order anyhow. Use usb_altnum_to_altsetting() to
- * look up an alternate setting in the altsetting array based on its number.

-/**
- * struct urb - USB Request Block
- * @urb_list: For use by current owner of the URB.
- * @anchor_list: membership in the list of an anchor
- * @anchor: to anchor URBs to a common mooring
- * @ep: Points to the endpoint's data structure. Will eventually
- * replace @pipe.
- * @pipe: Holds endpoint number, direction, type, and more.
- * Create these values with the eight macros available;
- * usb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is "ctrl"
- * (control), "bulk", "int" (interrupt), or "iso" (isochronous).
- * For example usb_sndbulkpipe() or usb_rcvintpipe(). Endpoint
- * numbers range from zero to fifteen. Note that "in" endpoint two
- * is a different endpoint (and pipe) from "out" endpoint two.
- * The current configuration controls the existence, type, and
- * maximum packet size of any given endpoint.
- * @dev: Identifies the USB device to perform the request.
- * @status: This is read in non-iso completion functions to get the
- * status of the particular request. ISO requests only use it
- * to tell whether the URB was unlinked; detailed status for
- * each frame is in the fields of the iso_frame-desc.
- * @transfer_flags: A variety of flags may be used to affect how URB
- * submission, unlinking, or operation are handled. Different
- * kinds of URB can use different flags.
- * @transfer_buffer: This identifies the buffer to (or from) which
- * the I/O request will be performed (unless URB_NO_TRANSFER_DMA_MAP
- * is set). This buffer must be suitable for DMA; allocate it with
- * kmalloc() or equivalent. For transfers to "in" endpoints, contents
- * of this buffer will be modified. This buffer is used for the data
- * stage of control transfers.
- * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP,
- * the device driver is saying that it provided this DMA address,
- * which the host controller driver should use in preference to the
- * transfer_buffer.
- * @transfer_buffer_length: How big is transfer_buffer. The transfer may
- * be broken up into chunks according to the current maximum packet
- * size for the endpoint, which is a function of the configuration
- * and is encoded in the pipe. When the length is zero, neither
- * transfer_buffer nor transfer_dma is used.
- * @actual_length: This is read in non-iso completion functions, and
- * it tells how many bytes (out of transfer_buffer_length) were
- * transferred. It will normally be the same as requested, unless
- * either an error was reported or a short read was performed.
- * The URB_SHORT_NOT_OK transfer flag may be used to make such
- * short reads be reported as errors.
- * @setup_packet: Only used for control transfers, this points to eight bytes
- * of setup data. Control transfers always start by sending this data
- * to the device. Then transfer_buffer is read or written, if needed.
- * @setup_dma: For control transfers with URB_NO_SETUP_DMA_MAP set, the
- * device driver has provided this DMA address for the setup packet.
- * The host controller driver should use this in preference to
- * setup_packet.
- * @start_frame: Returns the initial frame for isochronous transfers.
- * @number_of_packets: Lists the number of ISO transfer buffers.
- * @interval: Specifies the polling interval for interrupt or isochronous
- * transfers. The units are frames (milliseconds) for for full and low
- * speed devices, and microframes (1/8 millisecond) for highspeed ones.
- * @error_count: Returns the number of ISO transfers that reported errors.
- * @context: For use in completion functions. This normally points to
- * request-specific driver context.
- * @complete: Completion handler. This URB is passed as the parameter to the
- * completion function. The completion function may then do what
- * it likes with the URB, including resubmitting or freeing it.
- * @iso_frame_desc: Used to provide arrays of ISO transfer buffers and to
- * collect the transfer status for each buffer.
- *
- * This structure identifies USB transfer requests. URBs must be allocated by
- * calling usb_alloc_urb() and freed with a call to usb_free_urb().
- * Initialization may be done using various usb_fill_*_urb() functions. URBs
- * are submitted using usb_submit_urb(), and pending requests may be canceled
- * using usb_unlink_urb() or usb_kill_urb().
- *
- * Data Transfer Buffers:
- *
- * Normally drivers provide I/O buffers allocated with kmalloc() or otherwise
- * taken from the general page pool. That is provided by transfer_buffer
- * (control requests also use setup_packet), and host controller drivers
- * perform a dma mapping (and unmapping) for each buffer transferred. Those
- * mapping operations can be expensive on some platforms (perhaps using a dma
- * bounce buffer or talking to an IOMMU),
- * although they're cheap on commodity x86 and ppc hardware.
- *
- * Alternatively, drivers may pass the URB_NO_xxx_DMA_MAP transfer flags,
- * which tell the host controller driver that no such mapping is needed since
- * the device driver is DMA-aware. For example, a device driver might
- * allocate a DMA buffer with usb_alloc_coherent() or call usb_buffer_map().
- * When these transfer flags are provided, host controller drivers will
- * attempt to use the dma addresses found in the transfer_dma and/or
- * setup_dma fields rather than determining a dma address themselves. (Note
- * that transfer_buffer and setup_packet must still be set because not all
- * host controllers use DMA, nor do virtual root hubs).
- *
- * Initialization:
- *
- * All URBs submitted must initialize the dev, pipe, transfer_flags (may be
- * zero), and complete fields. All URBs must also initialize
- * transfer_buffer and transfer_buffer_length. They may provide the
- * URB_SHORT_NOT_OK transfer flag, indicating that short reads are
- * to be treated as errors; that flag is invalid for write requests.
- *
- * Bulk URBs may
- * use the URB_ZERO_PACKET transfer flag, indicating that bulk OUT transfers
- * should always terminate with a short packet, even if it means adding an
- * extra zero length packet.
- *
- * Control URBs must provide a setup_packet. The setup_packet and
- * transfer_buffer may each be mapped for DMA or not, independently of
- * the other. The transfer_flags bits URB_NO_TRANSFER_DMA_MAP and
- * URB_NO_SETUP_DMA_MAP indicate which buffers have already been mapped.
- * URB_NO_SETUP_DMA_MAP is ignored for non-control URBs.
- *
- * Interrupt URBs must provide an interval, saying how often (in milliseconds
- * or, for highspeed devices, 125 microsecond units)
- * to poll for transfers. After the URB has been submitted, the interval
- * field reflects how the transfer was actually scheduled.
- * The polling interval may be more frequent than requested.
- * For example, some controllers have a maximum interval of 32 milliseconds,
- * while others support intervals of up to 1024 milliseconds.
- * Isochronous URBs also have transfer intervals. (Note that for isochronous
- * endpoints, as well as high speed interrupt endpoints, the encoding of
- * the transfer interval in the endpoint descriptor is logarithmic.
- * Device drivers must convert that value to linear units themselves.)
- *
- * Isochronous URBs normally use the URB_ISO_ASAP transfer flag, telling
- * the host controller to schedule the transfer as soon as bandwidth
- * utilization allows, and then set start_frame to reflect the actual frame
- * selected during submission. Otherwise drivers must specify the start_frame
- * and handle the case where the transfer can't begin then. However, drivers
- * won't know how bandwidth is currently allocated, and while they can
- * find the current frame using usb_get_current_frame_number () they can't
- * know the range for that frame number. (Ranges for frame counter values
- * are HC-specific, and can go from 256 to 65536 frames from "now".)
- *
- * Isochronous URBs have a different data transfer model, in part because
- * the quality of service is only "best effort". Callers provide specially
- * allocated URBs, with number_of_packets worth of iso_frame_desc structures
- * at the end. Each such packet is an individual ISO transfer. Isochronous
- * URBs are normally queued, submitted by drivers to arrange that
- * transfers are at least double buffered, and then explicitly resubmitted
- * in completion handlers, so
- * that data (such as audio or video) streams at as constant a rate as the
- * host controller scheduler can support.
- *
- * Completion Callbacks:
- *
- * The completion callback is made in_interrupt(), and one of the first
- * things that a completion handler should do is check the status field.
- * The status field is provided for all URBs. It is used to report
- * unlinked URBs, and status for all non-ISO transfers. It should not
- * be examined before the URB is returned to the completion handler.
- *
- * The context field is normally used to link URBs back to the relevant
- * driver or request state.
- *
- * When the completion callback is invoked for non-isochronous URBs, the
- * actual_length field tells how many bytes were transferred. This field
- * is updated even when the URB terminated with an error or was unlinked.
- *
- * ISO transfer status is reported in the status and actual_length fields
- * of the iso_frame_desc array, and the number of errors is reported in
- * error_count. Completion callbacks for ISO transfers will normally
- * (re)submit URBs to ensure a constant transfer rate.
- *
- * Note that even fields marked "public" should not be touched by the driver
- * when the urb is owned by the hcd, that is, since the call to
- * usb_submit_urb() till the entry into the completion routine.
