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

Pull SCSI fixes from James Bottomley:
 "Four small fixes: three in drivers and one in the core.

  The core fix is also minor in scope since the bug it fixes is only
  known to affect systems using SCSI reservations. Of the driver bugs,
  the libsas one is the most major because it can lead to multiple disks
  on the same expander not being exposed"
