I am afraid that is just an assumption we cannot make. The user may just as well be reading a device state before a device is being used as that may matter.
the driver to do something on their behalf. The fact that the user is initiating an action through an interface which intended for debugging should not matter (and the user always has the option to check the runtime pm state before initiating the action if that matters at all).
1. That is a race condition. 2. Quite a lot of bugs we are looking at involve power transitions. You just cannot assume that a device will react the same way if it was waken up between events. Regards Oliver
