    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"
