As I mentioned earlier, this really belongs in struct pwm_chip rather
than struct pwm_ops. I know that Uwe said this is unlikely to happen,
and that may be true, but at the same time it's not like I'm asking
much. Whether you put this in struct pwm_ops or struct pwm_chip is
about the same amount of code, and putting it into pwm_chip is much
more flexible, so it's really a no-brainer.
