Merge tag 'char-misc-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver update from Greg Kroah-Hartman:
 "Here's the big char / misc driver update for 3.10-rc1

  A number of various driver updates, the majority being new
  functionality in the MEI driver subsystem (it's now a subsystem, it
  started out just a single driver), extcon updates, memory updates,
  hyper-v updates, and a bunch of other small stuff that doesn't fit in
  any other tree.

  All of these have been in linux-next for a while"
