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 (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr,
  mpt3sas, target). The biggest change (from my biased viewpoint) being
  that the mpi3mr now attached to the SAS transport class, making it the
  first fusion type device to do so.

  Beyond the usual bug fixing and security class reworks, there aren't a
  huge number of core changes"
