Pull more SCSI updates from James Bottomley:
 "This is the set of changes collected since just before the merge
  window opened. It's mostly minor fixes in drivers.

  The one non-driver set is the three optical disk (sr) changes where
  two are error path fixes and one is a helper conversion.

  The big driver change is the hpsa compat_alloc_userspace rework by Al
  so he can kill the remaining user. This has been tested and acked by
  the maintainer"
