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

Pull LED subsystem changes from Bryan Wu:
 "LED subsystem updates for 3.13 are basically cleanup and also add a
  new driver for PCA9685"

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds:
  leds: lp55xx: handle enable pin in driver
  leds-gpio: of: led should not be created if its status is disabled
  of: introduce of_get_available_child_count
  leds: Added driver for the NXP PCA9685 I2C chip
  leds: pwm: Remove redundant of_match_ptr
  leds: Include linux/of.h header
  leds: dac124s085: Remove redundant spi_set_drvdata
  leds: lp55xx: enable setting default trigger
  leds: blinkm: Remove redundant break
