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

Pull SCSI fixes from James Bottomley:
 "Ten patches, eight in drivers and two in the core, which correct a
  regression from directory removal and add a no VPD size quirk also to
  fix a regression. All pretty small"
