Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds
Pull LED subsystem updates from Bryan Wu: - move LED trigger drivers into a new directory - lp55xx common driver updates - other led drivers updates and bug fixing * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds: leds: leds-asic3: switch to using SIMPLE_DEV_PM_OPS leds: leds-bd2802: add CONFIG_PM_SLEEP to suspend/resume functions leds: lp55xx: configure the clock detection leds: lp55xx: use common clock framework when external clock is used leds: leds-ns2: fix oops at module removal leds: leds-pwm: Defer led_pwm_set() if PWM can sleep leds: lp55xx: fix the sysfs read operation leds: lm355x, lm3642: support camera LED triggers for flash and torch leds: add camera LED triggers leds: trigger: use inline functions instead of macros leds: tca6507: Use of_match_ptr() macro leds: wm8350: Complain if we fail to reenable DCDC leds: renesas: set gpio_request_one() flags param correctly leds: leds-ns2: set devm_gpio_request_one() flags param correctly leds: leds-lt3593: set devm_gpio_request_one() flags param correctly leds: leds-bd2802: remove erroneous __exit annotation leds: atmel-pwm: remove erroneous __exit annotation leds: move LED trigger drivers into new subdirectory leds: add new LP5562 LED driver
