Re: [PATCH v3 1/4] leds: leds-pwm: Convert to use devm_get_pwm

Update the driver to use the new API for requesting pwm so we can take
advantage of the pwm_lookup table to find the correct pwm to be used for the
LED functionality.
If the devm_get_pwm fails we fall back to legacy mode to try to get the pwm.
