Merge tag 'char-misc-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull Char/Misc driver merge from Greg Kroah-Hartman:
 "Here is the "big" char/misc driver patches for 3.8-rc1.  I'm starting
  to put random driver subsystems that I had previously sent you through
  the driver-core tree in this tree, as it makes more sense to do so.

  Nothing major here, the various __dev* removals, some mei driver
  updates, and other random driver-specific things from the different
  maintainers and developers.

  Note, some MFD drivers got added through this tree, and they are also
  coming in through the "real" MFD tree as well, due to some major
  mis-communication between me and the different developers.  If you
  have any merge conflicts, take the ones from the MFD tree, not these
  ones, sorry about that.

  All of this has been in linux-next for a while.

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"

Fix up trivial conflict in drivers/mmc/host/Kconfig due to new drivers
having been added (both at the end, as usual..)
