Here is the original code:
---------------------
	/* Copy hsm_progress struct */
	req_hpk = req_capsule_client_get(&req->rq_pill, &RMF_MDS_HSM_PROGRESS);
	if (req_hpk == NULL) {
		rc = -EPROTO;
		goto out;
	}

	*req_hpk = *hpk;
	req_hpk->hpk_errval = lustre_errno_hton(hpk->hpk_errval);

	ptlrpc_request_set_replen(req);

	rc = mdc_queue_wait(req);
	goto out;
out:
	ptlrpc_req_finished(req);
	return rc;
}
---------------------

I think if the last goto out; is to be removed,
then it should be replaced by a blank line.

It separates the last operation block from the return.

cheers, Joe
