Personally I find the change unnecessary and pointless, which is why I
didn't ack it. Even if function names were deemed important enough, keeping
pwm_apply_state() for the time being and just adding pwm_apply_might_sleep()
as duplicate would have done it, all the changes could have gone in long
ago, and per-subsystem cleanup could have been orthogonal.

I refrained from commenting because it might be considered bike shedding,
but I don't want to ack something I deem unnecessary and pointless without
comment. But then don't want to keep arguing either, so
