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

Pull SCSI fixes from James Bottomley:
 "Two small fixes: one in drivers (qla2xxx), and one in the core (sd) to
  try to cope with USB enclosures that silently change reported
  parameters"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: sd: Fix optimal I/O size for devices that change reported values
  scsi: qla2xxx: Fix I/Os being passed down when FC device is being deleted
