Merge tag 'leds_for_4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski: - userspace LED class driver - it can be useful for testing triggers and can also be used to implement virtual LEDs - LED class driver for NIC78bx device - LED core fixes for preventing potential races while setting brightness when software blinking is enabled - improvements in LED documentation to mention semantics on changing brightness while trigger is active * tag 'leds_for_4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds: leds: pca955x: Add ACPI support leds: netxbig: fix module autoload for OF registration leds: pca963x: Add ACPI support leds: leds-cobalt-raq: use builtin_platform_driver led: core: Fix blink_brightness setting race led: core: Use atomic bit-field for the blink-flags leds: Add user LED driver for NIC78bx device leds: verify vendor and change license in mlxcpld driver leds: pca963x: enable low-power state leds: pca9532: Use default trigger value from platform data leds: pca963x: workaround group blink scaling issue cleanup LED documentation and make it match reality leds: lp3952: Export I2C module alias information for module autoload leds: mc13783: Fix MC13892 keypad led access ledtrig-cpu.c: fix english leds/leds-lp5523.txt: make documentation match reality tools/leds: Add uledmon program for monitoring userspace LEDs leds: Use macro for max device node name size leds: Introduce userspace LED class driver mfd: qcom-pm8xxx: Clean up PM8XXX namespace
