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

Pull more SCSI updates from James Bottomley:
 "Mostly small stragglers that missed the initial merge.

  Driver updates are qla2xxx and smartpqi (mp3sas has a high diffstat
  due to the volatile qualifier removal, fnic due to unused function
  removal and sd.c has a lot of code shuffling to remove forward
  declarations)"

* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (38 commits)
  scsi: ufs: core: No need to update UPIU.header.flags and lun in advanced RPMB handler
