Merge tag 'staging-4.11-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull staging/IIO driver fixes from Greg KH:
 "Here are a few small staging and IIO driver fixes for issues that
  showed up after the big set if changes you merged last week.

  Nothing major, just small bugs resolved in some IIO drivers, a lustre
  allocation fix, and some RaspberryPi driver fixes for reported
  problems, as well as a MAINTAINERS entry update.

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