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

Pull SCSI updates from James Bottomley:
 "This pull includes driver updates from the usual suspects (stex, hpsa,
  ncr5380, scsi_dh, qla2xxx, be2iscsi, hisi_sas, cxlflash, aacraid,
  mp3sas, megaraid_sas, ibmvscsi, ufs) plus an assortment of
  miscellaneous fixes.

  The major user visible change of this pull is that we've moved from
  monotonically increasing host number to an ida allocated one (meaning
  the numbers get re-used) because someone managed to wrap the count in
  an iscsi system.  We don't believe there will be any adverse
  consequences of this"
