Sure, but for this bridge it's not needed - with that fix we get the
right data out of bridge response. Note
+sda: missing header in MODE_SENSE response
and
+SCSI device sda: drive cache: write back
in that diff. The former is exactly what we get when we detect that
sort of breakage (bare page 6 without header) and the latter is where
we manage to get the cache type.
