From: Vladimir Oltean <vladimir.olt...@nxp.com> This snippet of code has a bothering "if (...) return 0" in it which assumes it is the last piece of code running in dsa_port_probe().
This makes it difficult to add further code at the end of dsa_port_probe() which does not depend on MAC address stuff. So move the code to a dedicated function which returns void and let the code flow through.
