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

Pull SCSI updates from James Bottomley:
 "This is mostly update of the usual drivers: qla2xxx, qedf, smartpqi,
  hpsa, lpfc, ufs, mpt3sas, ibmvfc and hisi_sas. Plus number of minor
  changes, spelling fixes and other trivia"
