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

Pull SCSI updates from James Bottomley:
 "This update includes the usual round of major driver updates
  (hisi_sas, ufs, fnic, cxlflash, be2iscsi, ipr, stex). There's also the
  usual amount of cosmetic and spelling stuff"
