No, that's not right.  Disregard the above.

If the PWM device in question is already known to the kernel, then
before you call pwm_register() you must set pwm->dev to the address of
that device structure.  I need to come up with a better way to handle this.

If the PWM device isn't already known to the kernel as a true struct
device, then I don't yet have a Plan B.  Drat.  :(
