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)"
