From b55b1d50b08ce3b79329f62da8104b25c607bf38 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Tue, 8 Jun 2021 16:10:37 +0300 Subject: net: stmmac: fix NPD with phylink_set_pcs if there is no MDIO bus priv->plat->mdio_bus_data is optional, some platforms may not set it, however we proceed to look straight at priv->plat->mdio_bus_data->has_xpcs. Since the xpcs is instantiated based on the has_xpcs property, we can avoid looking at the priv->plat->mdio_bus_data structure altogether and just check for the presence of the xpcs pointer.
