Merge tag 'staging-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging driver updates from Greg KH:
 "Here is the "boring" staging driver update for 6.3-rc1.

  Nothing major in here at all, it's just lots of tiny code cleanups to
  bring some of the staging drivers more in line with the real portion
  of the kernel (apis and coding style.) Overall we remove more lines of
  code than we add, always a nice result.

  The big work was done by Martin Kaiser and Philipp Hortmann, both
  tackling some of the older wifi drivers, removing unused code and
  structures and a file in one case.

  Full details of the changes are in the shortlog.

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