Merge tag 'char-misc-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char / misc driver patches from Greg KH:
 "Here's the big driver misc / char pull request for 3.17-rc1.

  Lots of things in here, the thunderbolt support for Apple laptops,
  some other new drivers, testing fixes, and other good things.  All
  have been in linux-next for a long time"
