Merge tag 'staging-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO updates from Greg KH:
 "Here's the "big" staging/iio pull request for 4.10-rc1.

  Not as big as 4.9 was, but still just over a thousand changes. We
  almost broke even of lines added vs. removed, as the slicoss driver
  was removed (got a "clean" driver for the same hardware through the
  netdev tree), and some iio drivers were also dropped, but I think we
  ended up adding a few thousand lines to the source tree in the end.
  Other than that it's a lot of minor fixes all over the place, nothing
  major stands out at all.

  All of these have been in linux-next for a while. There will be a
  merge conflict with Al's vfs tree in the lustre code, but the
  resolution for that should be pretty simple, that too has been in
  linux-next"
