Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds

Pull LED subsystem updates from Bryan Wu:
 "In this cycle, we merged some fix and update for LED Flash class
  driver.  Then the core code of LED Flash class driver is in the kernel
  now.  Moreover, we also got some bug fixes, code cleanup and new
  drivers for LED controllers"

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds:
  leds: Don't treat the LED name as a format string
  leds: Use log level warn instead of info when telling about a name clash
  leds/led-class: Handle LEDs with the same name
  leds: lp8860: Fix typo in MODULE_DESCRIPTION in leds-lp8860.c
  leds: lp8501: Fix typo in MODULE_DESCRIPTION in leds-lp8501.c
  DT: leds: Add uniqueness requirement for 'label' property.
  dt-binding: leds: Add common LED DT bindings macros
  leds: add Qualcomm PM8941 WLED driver
  leds: add DT binding for Qualcomm PM8941 WLED block
  leds: pca963x: Add missing initialiation of struct led_info.flags
  leds: flash: Fix the size of sysfs_groups array
  Documentation: leds: Add description of LED Flash class extension
  leds: flash: document sysfs interface
  leds: flash: Remove synchronized flash strobe feature
  leds: Introduce devres helper for led_classdev_register
  leds: lp8860: make use of devm_gpiod_get_optional
  leds: Let the binding document example for leds-gpio follow the gpio bindings
  leds: flash: remove stray include directive
  leds: leds-pwm: drop one pwm_get_period() call
