That will definitely solve the suspend/resume issue we're having. But due to /sys/devices/.../power/control, we will still have to bypass runtime PM for this particular device. We need a way to unconditionally power down the device, and as long as runtime PM can be disabled by the user, we can't use it. Thanks, Ohad.
