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"

+Binding for ISSI IS31FL32xx and Si-En SN32xx LED Drivers
+
+The IS31FL32xx/SN32xx family of LED drivers are I2C devices with multiple
+constant-current channels, each with independent 256-level PWM control.
+Each LED is represented as a sub-node of the device.
+
+Required properties:
+- compatible: one of
+	issi,is31fl3236
+	issi,is31fl3235
+	issi,is31fl3218
+	issi,is31fl3216
+	si-en,sn3218
+	si-en,sn3216
+- reg: I2C slave address
+- address-cells : must be 1
+- size-cells : must be 0
+
+LED sub-node properties:
+- reg : LED channel number (1..N)
+- label :  (optional)
+  see Documentation/devicetree/bindings/leds/common.txt
+- linux,default-trigger :  (optional)
+  see Documentation/devicetree/bindings/leds/common.txt
+
+
+Example:
+
+is31fl3236: led-controller@3c {
+	compatible = "issi,is31fl3236";
+	reg = <0x3c>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	led@1 {
+		reg = <1>;
+		label = "EB:blue:usr0";
+	};
+	led@2 {
+		reg = <2>;
+		label = "EB:blue:usr1";
+	};
+	...
+	led@36 {
+		reg = <36>;
+		label = "EB:blue:usr35";
+	};
+};
