As - mutex_lock calls might_sleep and sleeping is not allowed in atomic contexts - we have to switch to spinlocks here. - -Signed-Off-By: Holger Freyther ---- - drivers/leds/leds-neo1973-gta02.c | 10 +++++----- - 1 files changed, 5 insertions(+), 5 deletions(-) - -diff --git a/drivers/leds/leds-neo1973-gta02.c b/drivers/leds/leds-neo1973-gta02.c -index 952ad69..8fe817b 100644 ---- a/drivers/leds/leds-neo1973-gta02.c -+++ b/drivers/leds/leds-neo1973-gta02.c -@@ -27,7 +27,7 @@ - - struct gta02_led_priv - { -- struct mutex mutex; -+ spinlock_t lock; - struct led_classdev cdev; - struct s3c2410_pwm pwm; - unsigned int gpio; -@@ -53,6 +53,7 @@ static inline struct gta02_led_bundle *to_bundle(struct led_classdev *led_cdev) - static void gta02led_set(struct led_classdev *led_cdev, - enum led_brightness value) - { -+ unsigned long flags; - struct gta02_led_priv *lp = to_priv(led_cdev); - - /* -@@ -60,7 +61,7 @@ static void gta02led_set(struct led_classdev *led_cdev, - * value == 128 -> 50% duty cycle (medium power) - * value == 0 -> 0% duty cycle (zero power) - */ -- mutex_lock(&lp->mutex); -+ spin_lock_irqsave(&lp->lock, flags); - - if (lp->has_pwm) { - s3c2410_pwm_duty_cycle(value, &lp->pwm); -@@ -68,7 +69,7 @@ static void gta02led_set(struct led_classdev *led_cdev, - neo1973_gpb_setpin(lp->gpio, value ? 1 : 0); - } - -- mutex_unlock(&lp->mutex); -+ spin_unlock_irqrestore(&lp->lock, flags); - } - - #ifdef CONFIG_PM -@@ -170,7 +171,7 @@ static int __init gta02led_probe(struct platform_device *pdev) - break; - } - -- mutex_init(&lp->mutex); -+ spin_lock_init(&lp->lock); - rc = led_classdev_register(&pdev->dev, &lp->cdev); - } - -@@ -192,7 +193,6 @@ static int gta02led_remove(struct platform_device *pdev) - gta02led_set(&lp->cdev, 0); - - led_classdev_unregister(&lp->cdev); -- mutex_destroy(&lp->mutex); - } - - platform_set_drvdata(pdev, NULL); --- -1.5.6.5 - -- cgit v1.2.3
