Subject: [PATCH 5.10 061/105] net: axienet: setup mdio unconditionally
From: Andy Chiu <andy.chiu@...ive.com>
[ Upstream commit d1c4f93e3f0a023024a6f022a61528c06cf1daa9 ]
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 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.
