I suggest to choose another imperative wording for your change description.
Will the tag âFixesâ become helpful for the commit message?

How do you think about the following code variant with the addition
of a jump target?

 		err = alloc_ud_wq_attr(qp, rdi->dparms.node);
 		if (err) {
 			ret = (ERR_PTR(err));
-			goto bail_driver_priv;
+			goto bail_free_rq;
 		}

 bail_rq_wq:
-	rvt_free_rq(&qp->r_rq);
 	free_ud_wq_attr(qp);
+
+bail_free_rq:
+	rvt_free_rq(&qp->r_rq);

 bail_driver_priv:
