Merge tag 'staging-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging / IIO driver updates from Greg KH:
 "Here is the big set of IIO and staging driver patches for 5.14-rc1.

  Loads of IIO driver updates and additions in here, the shortlog has
  the full details.

  For the staging side, we moved a few drivers out of staging, and
  deleted the kpc2000 drivers as the original developer asked us to
  because no one was working on them anymore.

  Also in here are loads of coding style cleanups due to different
  intern projects focusing on the staging tree to try to get experience
  doing kernel development.

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