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 updates of the usual suspects: lpfc, qla2xxx, bnx2fc,
  qedf, hpsa, hisi_sas, smartpqi, cxlflash, aacraid, csiostor along with
  a host of minor and miscellaneous changes"
