Uwe Kleine-König	2b7b6d44e2	leds: timer trigger: simplifications from core changes ... The trigger core learned error handling for the activate callback and can handle device attributes now. This allows simplifying the driver considerably. Note that .deactivate() is only called when .activate() succeeded, so the check for .trigger_data being non-NULL can go away.

Uwe Kleine-König	2282e125a4	leds: triggers: let struct led_trigger::activate() return an error code ... Given that activating a trigger can fail, let the callback return an indication. This prevents to have a trigger active according to the "trigger" sysfs attribute but not functional. All users are changed accordingly to return 0 for now. There is no intended change in behaviour.

Uwe Kleine-König	033692eb3e	leds: triggers: make the MODULE_LICENSE string match the actual license ... These files are licensed under GPL version 2 only. So use "GPL v2" instead of "GPL" (which means v2 or later). Also remove an empty (but commented) line at the end of the license header which nicely proves in the context that the drivers are really v2 only :-) Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Jacek Anaszewski <jacek.anaszewski@gmail.com>	2018-07-05 22:59:36 +02:00
Kim, Milo	f07fb52107	leds: move LED trigger drivers into new subdirectory ... For better driver management, new subdirectory, 'trigger' is created. All LED trigger drivers are moved into this directory. Internal header, 'leds.h' is included in each LED trigger drivers. Fix the location of header file, "leds.h" -> "../leds.h" in driver files. One exception is here, 'ledtrig-timer.c'. There is no need to include 'leds.h'. so '#include "leds.h"' line was removed.
