The way to do this right is one-subsystem-at-a-time, right?  Why not
start there, doing it cleanly, and then at the end, change the driver
core and then just the subsystem pointers?  That should be much simpler,
easier to review and verify, and many more changes (and probably take a
kernel release or two to get through.)

thanks,
