Merge tag 'char-misc-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char / misc driver updates from Greg KH:
 "Here is the big char/misc driver update for 5.11-rc1.

  Continuing the tradition of previous -rc1 pulls, there seems to be
  more and more tiny driver subsystems flowing through this tree.

  Lots of different things, all of which have been in linux-next for a
  while with no reported issues:

   - extcon driver updates

   - habannalab driver updates

   - mei driver updates

   - uio driver updates

   - binder fixes and features added

   - soundwire driver updates

   - mhi bus driver updates

   - phy driver updates

   - coresight driver updates

   - fpga driver updates

   - speakup driver updates

   - slimbus driver updates

   - various small char and misc driver updates"
