…it/jejb/scsi

Pull SCSI fixes from James Bottomley:
 "This is mostly a set of minor and obvious fixes (three in one of the
  new drivers).

  The only substantial change is to move the ufs to the blk-mq now that
  the merge window fixed the suspend/resume issues with blk-mq"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: qla2xxx: Initialize port speed to avoid setting lower speed
  Revert "scsi: ufs: Disable blk-mq for now"
  scsi: NCR5380: Return false instead of NULL
  scsi: qla2xxx: Fix a typo in MODULE_PARM_DESC
  scsi: hisi_sas: Remove set but not used variable 'dq_list'
  scsi: myrs: only build on little-endian platforms
  scsi: myrs: avoid stack overflow warning
  scsi: lpfc: fix remoteport access
  scsi: myrb: fix sprintf buffer overflow warning
  scsi: target/core: Avoid that a kernel oops is triggered when COMPARE AND WRITE fails
