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

Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (scsi_debug, ufs, lpfc, st, fnic, mpi3mr,
  mpt3sas) and the removal of cxlflash.

  The only non-trivial core change is an addition to unit attention
  handling to recognize UAs for power on/reset and new media so the tape
  driver can use it"
