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

Pull SCSI fixes from James Bottomley:
 "Nine minor fixes, seven in drivers and two in the core SCSI disk
  driver (sd) which should be harmless involving removing an unused
  variable and quietening a spurious warning"
Signed-off-by: James E.J. Bottomley <jejb@linux.ibm.com>
