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. :(
