Subject: [PATCH] Remove __dev* markings from init.h

Note, the below patch is now in my driver-core.next tree, and should go
to Linus before 3.8-final is out.  Just a heads-up for anyone who is
wondering what happened to the __dev* markings in the kernel.

Subject: [PATCH] Remove __dev* markings from init.h

Now that all in-kernel users of __dev* are gone, let's remove them from
init.h to keep them from popping up again and again.

Thanks to Bill Pemberton for doing all of the hard work to make removal
of this possible.
