Merge branch 'for-linus' of git://git.o-hand.com/linux-rpurdie-leds
* 'for-linus' of git://git.o-hand.com/linux-rpurdie-leds: leds: Futher document blink_set leds: Add options to have GPIO LEDs start on or keep their state leds: LED driver for National Semiconductor LP3944 Funlight Chip leds: pca9532 - Indent using tabs, not spaces. leds: Remove an orphan Kconfig entry leds: Further document parameters for blink_set() leds: alix-leds2 fixed for Award BIOS leds: leds-gpio - fix a section mismatch leds: add the sysfs interface into the leds-bd2802 driver for changing wave pattern and led current. leds: change the license information leds: fix led-bd2802 errors while resuming
