Hi David & Florian,

Just to clarify that I do not copy exactly from Florian.
I have changed it to have proper handling on mdio unregister
while netdev_register() failed as showed below:

	return 0;
 
-error_mdio_register:
-	unregister_netdev(ndev);
 error_netdev_register:
+	stmmac_mdio_unregister(ndev);
+error_mdio_register:
	netif_napi_del(&priv->napi);

Vs 

+
+       return ret;

 error_mdio_register:
-       unregister_netdev(ndev);
-error_netdev_register:
        netif_napi_del(&priv->napi);

Just to point it out here, so that Florian could aware if he/she submit
this fix to the mailing list.


Thanks & Regards,
Wilson
