Merge tag 'char-misc-4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc driver fixes from Greg KH:
 "A smattering of different small fixes for some random driver
  subsystems. Nothing all that major, just resolutions for reported
  issues and bugs.

  All have been in linux-next with no reported issues"
