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.

Fixed the subject line and applied, thanks.

It's not obvious to me what needed fixing here, and I don't find where
you the patches, neither in next nor in
https://git.kernel.org/pub/scm/linux/kernel/git/lee/backlight.git; so I
cannot check what you actually changed.

I assume you did s/lm3630a/lm3630a_bl/ ? I didn't because it felt
tautological.

Best regards
Uwe
