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, mpi3mr, mpt3sas, lpfc, fnic,
  hisi_sas, arcmsr, ) plus the usual assorted minor fixes and updates.

  This time around there's only a single line update to the core, so
  nothing major and barely anything minor"
