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
