Merge tag 'staging-4.14-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 

Pull staging and IIO fixes from Greg KH:
 "Here are a small number of patches to resolve some reported IIO and a
  staging driver problem. Nothing major here, full details are in the
  shortlog below.

  All have been in linux-next with no reported issues"
