Merge tag 'staging-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO updates from Greg KH:
 "Here's the large set of staging and iio driver patches for 4.13-rc1.

  After over 500 patches, we removed about 200 more lines of code than
  we added, not great, but we added some new IIO drivers for unsupported
  hardware, so it's an overall win.

  Also here are lots of small fixes, and some tty core api additions
  (with the tty maintainer's ack) for the speakup drivers, those are
  finally getting some much needed cleanups and are looking much better
  now than before. Full details in the shortlog.

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