Merge tag 'char-misc-5.9-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 large set of char and misc and other driver subsystem
  patches for 5.9-rc1. Lots of new driver submissions in here, and
  cleanups and features for existing drivers.

  Highlights are:
   - habanalabs driver updates
   - coresight driver updates
   - nvmem driver updates
   - huge number of "W=1" build warning cleanups from Lee Jones
   - dyndbg updates
   - virtbox driver fixes and updates
   - soundwire driver updates
   - mei driver updates
   - phy driver updates
   - fpga driver updates
   - lots of smaller individual misc/char driver cleanups and fixes

  Full details are in the shortlog.

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