Merge tag 'char-misc-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver updates from Greg KH:
 "Here's the big char/misc driver update for 3.19-rc1

  Lots of little things all over the place in different drivers, and a
  new subsystem, "coresight" has been added.  Full details are in the
  shortlog"
