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

Pull SCSI updates from James Bottomley:
 "This series consists of the usual driver updates (ufs, ibmvfc,
  megaraid_sas, lpfc, elx, mpi3mr, qedi, iscsi, storvsc, mpt3sas) with
  elx and mpi3mr being new drivers.

  The major core change is a rework to drop the status byte handling
  macros and the old bit shifted definitions and the rest of the updates
  are minor fixes"
