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

Description:

		Reverse the blink logic. If set to 0 (default) blink on for

		delay_on ms, then blink off for delay_off ms, leaving the LED

		normally off. If set to 1, blink off for delay_off ms, then

		blink on for delay_on ms, leaving the LED normally on.

		Setting this value also immediately changes the LED state.

- default-state : The initial state of the LED. Valid values are "on", "off",

  and "keep". If the LED is already on or off and the default-state property is

  set the to same value, then no glitch should be produced where the LED

  momentarily turns off (or on). The "keep" setting will keep the LED at

  whatever its current state is, without producing a glitch.  The default is

  off if this property is not present.
