Note, this will not work. You can not only have "one" state for a system like this. That just broke any system with more than one controller, of which we have millions.
This has to be dynamic for any number of controllers in the system, like the sound and USB core can handle. Any requirement of "there can be only one!" will obviously never be acceptable as that is not how Linux works.
