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
