Subject[PATCH leds v1 01/10] leds: parse linux,default-trigger DT property in LED core
Date
Do parsing of `linux,default-trigger` DT property to LED core. Currently
it is done in many different drivers and the code is repeated.

This commit removes the parsing only from drivers where the removal is
simple, i.e. those which pass struct led_init_data with fwnode handle to
the LED classdev registering function.
