> Subject: [PATCH v8 net-next 1/4] net: axienet: setup mdio unconditionally
>
> The call to axienet_mdio_setup should not depend on whether "phy-node"
> pressents on the DT. Besides, since `lp->phy_node` is used if PHY is in SGMII or
:s/pressents/present
> 100Base-X modes, move it into the if statement. And the next patch will
> remove `lp->phy_node` from driver's private structure and do an of_node_put
> on it right away after use since it is not used elsewhere.
