Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED driver updates from Jacek Anaszewski:
"Three new LED class drivers and some minor fixes and improvementes to
the leds-gpio driver, LED Trigger core and documentation"
* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds:
leds: triggers: Check return value of kobject_uevent_env()
leds: triggers: Return from led_trigger_set() if there is nothing to do
leds: gpio: fix and simplify error handling in gpio_leds_create
leds: gpio: switch to managed version of led_classdev_register
leds: gpio: fix and simplify reading property "label"
leds: gpio: simplify gpio_leds_create
leds: gpio: add helper cdev_to_gpio_led_data
leds: gpio: fix an unhandled error case in create_gpio_led
leds: gpio: introduce gpio_blink_set_t
leds: add driver for Mellanox systems LEDs
Documentation: move oneshot trigger attributes documentation to ABI
leds: centralize definition of "default-state" property
leds: add PM8058 LEDs driver
leds: pm8058: add device tree bindings
leds: do not overflow sysfs buffer in led_trigger_show
leds: make triggers explicitly non-modular
DT: leds: Add bindings for ISSI is31fl319x
leds: is31fl319x: 1/3/6/9-channel light effect led driver
