Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull more SCSI updates from James Bottomley:
"Updates that missed the first pull, mostly because of needing more
soak time.
Driver updates (zfcp, ufs, mpi3mr, plus two ipr bug fixes), an
enclosure services (ses) update (mostly bug fixes) and other minor bug
fixes and changes"
