Linus Torvalds cff2f741b8 Driver core updates for 3.8-rc1
Here's the large driver core updates for 3.8-rc1.
 
 The biggest thing here is the various __dev* marking removals.  This is
 going to be a pain for the merge with different subsystem trees, I know,
 but all of the patches included here have been ACKed by their various
 subsystem maintainers, as they wanted them to go through here.
 
 If this is too much of a pain, I can pull all of them out of this tree
 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.
 
 All of these have (much to Stephen's annoyance), been in linux-next for
 a while.
