Commit9e42f71526("drivers: net: cpsw: add phy-handle parsing") saved the "phy-handle" phandle into a new cpsw_priv field. However, phy connections are per-slave, so the phy_node field should be in cpsw_slave_data rather than cpsw_priv. This would go unnoticed in a single emac configuration. But in dual_emac mode, the last "phy-handle" property parsed for either slave would be used by both of them, causing them both to refer to the same phy_device.
