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, qla2xxx, libsas).

  The major core change is a rework to remove the two helpers around
  scsi_execute_cmd and use it as the only submission interface along
  with other minor fixes and updates"
