Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Twelve minor fixes, all in drivers or doc.
Most of the fixes are pretty obvious (although we had two goes to get
the UFS sysfs doc right) and the biggest change is in the ufs driver
which they've extensively tested"
