Merge tag 'char-misc-5.8-rc6' of...

Merge tag 'char-misc-5.8-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc into master

Pull char/misc fixes from Greg KH:
 "Here are number of small char/misc driver fixes for 5.8-rc6

  Not that many complex fixes here, just a number of small fixes for
  reported issues, and some new device ids. Nothing fancy.

  All of these have been in linux-next for a while with no reported
  issues"
