2012-06-12leds: don't disable blinking when writing the same value to delay_on or ↵Rafal Prylowski
delay_off Function led_set_software_blink() assumes that blink timer is still running, but commit 488bc35bf40df89d37486c1826b178a2fba36ce7 introduced disabling of blink timer before each call to led_set_software_blink(). Correct led_software_blink(): 1) remove protection against reprogramming blink timer to the same values, because it only disables blinking now, 2) remove unnecessary call to led_stop_software_blink().

2008-04-24leds: Cleanup various whitespace and code style issuesNémeth Márton
Break the lines which were more than 80 characters into more lines; replace SPACEs with TABs; correct ident at switch-case; change character encoding from ISO-8859-2 to UTF-8. The order of the functions in led-triggers.c changed in order the similar functions can still be together under titles "Used by LED Class", "LED Trigger Interface" and "Simple LED Tigger Interface" as was grouped before when exported with EXPORT_SYMBOL.

2006-06-27[PATCH] spin/rwlock init cleanupsIngo Molnar
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 classRichard Purdie
Add the foundations of a new LEDs subsystem. This patch adds a class which presents LED devices within sysfs and allows their brightness to be controlled.
