Commit "8b63ec1837fa phylib: Make PHYs children of their MDIO bus, not
the bus' parent." broke finding PHY properties in the MAC device tree
node. The parent device is now the MDIO bus, not the MAC. Use
attached_dev towards the MAC device tree node.
Fixes: 8b63ec1837fa ("phylib: Make PHYs children of their MDIO bus, not the
bus' parent.")
