I already lost any hope to merge this to linux-3.18, so no problem.

Could you and Rob explain me this compatible issue? I got a feeling that
Rob telling me to keep "airoha,en7581-snand" compatible while you are
telling the opposite. As for me the use of "airoha,en7523-snand" or
maybe "airoha,en75xx-snand" for both en7523 & en7581 chips is the best.

Is there any policy? Could you provide a link?
