Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (ufs, lpfc, hisi_sas, st).

  Amazingly enough, no core changes with the biggest set of driver
  changes being ufs (which conflicted with it's own fixes a bit, hence
  the merges) and the rest being minor fixes and updates"
