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,
  qla2xxx, hisi_sas, pm80xx) plus the removal of the gdth driver (which
  is bound to cause conflicts with a trivial change somewhere).

  The only big major rework of note is the one from Hannes trying to
  clean up our result handling code in the drivers to make it
  consistent"
