OK, so for now I'll just change them to take a (const) pointer to the
cdev as the argument - the rest they can get from there.

A patch adding them to thermal_cooling_device_[un]register() would be
separate, for the next cycle.  Where should they be called in there?
Under thermal_list_lock I suppose?

I'll send a replacement for the $subject patch later and I'll queue up
the rest of the series.

Thanks for the reviews!
