It wasn't as much as that, I was trying to keep runtime suspend simple.
In that the GT takes the wakelock to prevent suspend as required and
not have the knowledge about all the users of the device inside runtime
management callbacks. (It means the users then have to be concious that
if they don't hold an explicit wakelock, they should check rpm first.)
