Merge tag 'staging-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO driver updates from Greg KH:
 "Here is the large set of staging and IIO driver changes for 5.8-rc1

  Nothing major, but a lot of new IIO drivers are included in here,
  along with other core iio cleanups and changes.

  On the staging driver front, again, nothing noticable. No new
  deletions or additions, just a ton of tiny cleanups all over the tree
  done by a lot of different people. Most coding style, but many actual
  real fixes and cleanups that are nice to see.

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