Pull LED subsystem updates from Jacek Anaszewski:
 "Besides regular driver updates, we introduce a portion of LED core
  improvements, that allow to avoid the need for using work queues in
  the LED class drivers, that set brightness in a blocking way.

  Affected LED class drivers are being optimized accordingly.

   - LED core improvements:
        - use EXPORT_SYMBOL_GPL consistently,
        - add two new LED_BLINK_ flags,
        - rename brightness_set_sync op to brightness_set_blocking,
        - add led_set_brightness_nosleep{nopm} functions,
        - use set_brightness_work for the blocking op,
        - drivers shouldn't enforce SYNC/ASYNC brightness setting,
        - turn off the LED and wait for completion on unregistering LED
          class device,
        - add managed version of led_trigger_register,
        - add description of brightness setting API to the LED class doc.

   - Remove work queues from drivers: leds-tlc591xx, leds-88pm860x, leds-adp5520,
        leds-bd2802, leds-blinkm, leds-lm3533, leds-lm3642, leds-pca9532,
        leds-lp3944, leds-lp55xx, leds-lp8788, leds-lp8860, leds-pca955x,
        leds-pca963x, leds-wm831x, leds-da903x, leds-da9052, leds-dac124d085,
        leds-lt3593, leds-max8997, leds-mc13783, leds-regulator, leds-wm8350,
        leds-max77693, leds-aat1290, leds-ktd2692, leds-gpio, leds-pwm,
        leds-lm355x, leds-ns2.

   - Replace brightness_set op with a new brightness_set_blocking op to
     make the drivers compatible with led triggers: leds-ipaq-micro,
     leds-powernv.

   - Add missing of_node_put: leds-ktd2692, leds-aat1290, leds-max77693.

   - Make the driver explicitly non-modular: ledtrig-cpu,
     ledtrig-ide-disk, leds-syscon.

   - Improvements to leds-bcm6328:
        - reuse bcm6328_led_set() instead of copying its functionality,
        - swap LED ON and OFF definitions,
        - improve blink support,
        - simplify duplicated unlock in bcm6328_blink_set,
        - add little endian support,
        - remove unneded lock when checking initial LED status,
        - add HAS_IOMEM dependency,
        - code cleaning.

   - Improvements to leds-bcm6358:
        - use bcm6358_led_set() in order to get rid of the lock,
        - merge bcm6358_led_mode and bcm6358_led_set,
        - add little endian support,
        - remove unneded lock when checking initial LED status,
        - add HAS_IOMEM dependency,
        - remove unneeded busy status check.

   - Call led_pwm_set() in leds-pwm to enforce default LED_OFF.

   - Fix duration to be msec instead of jiffies: ledtrig-transient.

   - Removing NULL check: leds-powernv.

   - Use platform_register/unregister_drivers(): leds-sunfire.

   - Fix module license specification: ledtrig-oneshot.

   - Fix driver description and make license match the header: leds-pwm.

   - Remove checking for state < 1 in flash_strobe_store():
     led-class-flash.

   - Use led_set_brightness_sync for torch brightness:
     v4l2-flash-led-class"
