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, qla2xxx,
  target, smartpqi, lpfc, mpt3sas).

  The core change causing the most churn was replacing the command
  request field request with a macro, allowing us to offset map to it
  and remove the redundant field; the same was also done for the tag
  field.

  The most impactful change is the final removal of scsi_ioctl, which
  has been deprecated for over a decade"
