Merge tag 'leds_for_4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds

Pull LED updates from Jacek Anaszewski:
 "LED core improvements:
   - Fix misleading comment after workqueue removal from drivers
   - Avoid error message when a USB LED device is unplugged
   - Add helpers for calling brightness_set(_blocking)

  LED triggers:
   - Simplify led_trigger_store by using sysfs_streq()

  LED class drivers improvements:
   - Improve wording and formatting in a comment: lp3944
   - Fix return value check in create_gpio_led(): leds-gpio
   - Use GPIOF_OUT_INIT_LOW instead of hardcoded zero: leds-gpio
   - Use devm_led_classdev_register(): leds-lm3533, leds-lm3533,
     leds-lp8788, leds-wm831x-status, leds-s3c24xx, leds-s3c24xx,
     leds-max8997.

  New LED class driver:
   - Add driver for the ISSI IS31FL32xx family of LED controllers.

  Device Tree documentation:
   - of: Add vendor prefixes for Integrated Silicon Solutions Inc.
     (issi) and Si-En Technology (si-en).
   - DT: Add common bindings for Si-En Technology SN3216/18 and
     IS31FL32xx family of LED controllers, since they seem to be the
     same hardware, just rebranded"
