linux-leds@vger.kernel.org Since commit 141f15c66d94 ("leds: pwm: remove header") that platform interface is not usable from outside and there seems to be no in tree user anymore. All in-tree users of the leds-pwm driver seem to use DT currently. Getting rid of the old platform interface allows the leds-pwm driver to switch over from 'devm_led_classdev_register()' to 'devm_led_classdev_register_ext()'.
