    I guess, if nothing else, it would be nice to avoid the tables that
    we'd have to copy between DRM and cpufreq: the set of input devices
    that are likely a sign that the user is interacting with the device.
    It always seemed weird to copy that from place to place and if there's
    ever a new input device to add it would be annoying to have to update
    it everywhere.

    It would be nice to avoid some of the other boilerplate code here
    connecting things together when all we need is a callback, but I agree
    that if those were copied it wouldn't be the end of the world.
