Merge tag 'char-misc-5.3-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver fixes from Greg KH:
 "Here are some small char and misc driver fixes for reported issues for
  5.3-rc7

  Also included in here is the documentation for how we are handling
  hardware issues under embargo that everyone has finally agreed on, as
  well as a MAINTAINERS update for the suckers who agreed to handle the
  LICENSES/ files.

  All of these have been in linux-next last week with no reported
  issues"
