That is as it should be.  I thought you were talking about a successful call.
The out parameters are not examined when the return value is nonzero,
so it is correct to leave them unset.

-305 is MIG_NO_REPLY.  This is what it should be with the ds_routines.c
change I put in to fix the original bug you found.  The stub is behaving
fine.  The reply message should already have been sent by the
ds_device_write_error_reply call in ds_device_write.  What is the actual
failure mode now?
