This is likely going to break the build on your branch because
pwm_apply_might_sleep() is only available in the PWM tree right now. In
any case, I've now pushed a commit that adds pwm_apply_state() back as a
compatibility stub, so it should be okay for you to drop this if you
run into problems. It's always possible that somebody else wants to add
a new caller of pwm_apply_state() and in retrospect we should've
probably done this from the start, at least as a transitional measure
for one or two cycles.
