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, smartpqi, NCR5380, mac_scsi, lpfc,
  mpi3mr).

  There are no user visible core changes and a whole series of minor
  updates and fixes. The largest core change is probably the
  simplification of the workqueue allocation path"
