2007-12-31	leds: Fix leds_list_lock locking issues	Richard Purdie	1	-4/+4
	Covert leds_list_lock to a rw_sempahore to match previous LED trigger locking fixes, fixing lock ordering. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-12-07	leds: Fix led trigger locking bugs	Richard Purdie	1	-24/+25
	Convert part of the led trigger core from rw spinlocks to rw semaphores. We're calling functions which can sleep from invalid contexts otherwise. Fixes bug #9264. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-07-16	leds: Convert from struct class_device to struct device	Richard Purdie	1	-6/+7
	Convert the LEDs class from struct class_device to struct device since class_device is scheduled for removal. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-16	leds: Add warning printks in error paths	Richard Purdie	1	-2/+9
	Add warning printks if led_trigger_register_simple() fails. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-07-16	leds: Fix trigger unregister_simple if register_simple fails	Richard Purdie	1	-1/+2
	Fix led_trigger_unregister_simple to handle the case where led_trigger_register_simple fails, avoiding a NULL pointer dereference. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2006-10-01	[PATCH] leds: turn LED off when changing triggers	Paul Collins	1	-0/+1
	I was playing with LED triggers when I noticed that changing from heartbeat (or ide-disk) to "none" at the right moment would leave the LED stuck on. This is easy to reproduce by doing "find / >/dev/null" with the ide-disk trigger enabled and then switching to "none". Here is a patch that fixes the problem by explicitly turning the LED off after removing the existing trigger.

2006-06-27	[PATCH] spin/rwlock init cleanups	Ingo Molnar	1	-1/+1
	locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-03-31	[PATCH] LED: add LED trigger tupport	Richard Purdie	1	-0/+239
	Add support for LED triggers to the LED subsystem. "Triggers" are events which change the state of an LED. Two kinds of trigger are available, simple ones which can be added to exising code with minimum disruption and complex ones for implementing new or more complex functionality.
