Pull LED updates from Bryan Wu:
 "This cycle we got:
   - new driver for leds-mc13783
   - bug fixes
   - code cleanup"

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds:
  leds: make sure we unregister a trigger only once
  leds: leds-pwm: properly clean up after probe failure
  leds: clevo-mail: Make probe function __init
  leds-ot200: Fix dependencies
  leds-gpio: of: introduce MODULE_DEVICE_TABLE for module autoloading
  leds: clevo-mail: remove __initdata marker
  leds: leds-ss4200: remove __initdata marker
  leds: blinkm: remove unnecessary spaces
  leds: lp5562: remove unnecessary parentheses
  leds: leds-ss4200: remove DEFINE_PCI_DEVICE_TABLE macro
  leds: leds-s3c24xx: Trivial cleanup in header file
  drivers/leds: delete non-required instances of include <linux/init.h>
  leds: leds-gpio: add retain-state-suspended property
  leds: leds-mc13783: Add devicetree support
  leds: leds-mc13783: Remove unnecessary cleaning of registers on exit
  leds: leds-mc13783: Use proper "max_brightness" value fo LEDs
  leds: leds-mc13783: Use LED core PM functions
  leds: leds-mc13783: Add MC34708 LED support
  leds: Turn off led if blinking is disabled
  ledtrig-cpu: Handle CPU hot(un)plugging
