+Subject: [PATCH] leds: core: add OF variants of LED registering functions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+These new functions allow passing an additional device_node argument
+that will be internally set for created LED device. Thanks to this LED
+core code and triggers will be able to access DT node for reading extra
+info.
+
+The easiest solution for achieving this was reworking old functions to
+more generic ones & adding simple defines for API compatibility.

+Subject: [PATCH] leds: gpio: use OF variant of LED registering function
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In leds-gpio we support LEDs specified in DT so we should use
+(devm_)of_led_classdev_register. This allows passing DT node as argument
+for use by the LED subsystem.
