From 9ed8a41a30916a79529552872e8d1a6175d37398 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/9] rt2x00: Move Move pci_dev specific access to rt2x00pci
pci_dev->irq and pci_name(pci_dev) access should be limited
to rt2x00pci only. This is more generic and allows a rt2x00 pci
driver to be controlled as PCI device but also as platform driver
(needed for rt2800pci SoC support).
