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.
