Merge tag 'staging-4.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging fixes from Greg KH:
 "Here are three staging driver fixes for 4.15-rc6

  The first resolves a bug in the lustre driver that came about due to a
  broken cleanup patch, due to crazy list usage in that codebase.

  The remaining two are ion driver fixes, finally getting the CMA
  interaction to work properly, resolving two regressions in that area
  of the code.

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