Re: [PATCH v3 2/2] backlight: lm3630a: convert to atomic PWM API and check for errors

The practical upside here is that this only needs a single API call to program the hardware which (depending on the underlaying hardware) can be more effective and prevents glitches.

Up to now the return value of the pwm functions was ignored. Fix this and propagate the error to the caller.
