Merge tag 'char-misc-4.0-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver fixes from Greg KH:
 "Here are two char/misc fixes for 4.0-rc3.

  One is a reported binder driver fix needed due to a change in the mm
  core that happened in 4.0-rc1.  Another is a mei driver fix that
  resolves a reported issue in that driver.

  Both have been in linux-next for a while"
