If the phy interface mode is not found in devicetree, or if devicetree is not configured, of_get_phy_mode returns -ENODEV. The current code sets the phy interface mode to the return value from of_get_phy_mode without checking if it is valid. This invalid phy interface mode is passed as parameter to of_phy_connect or to phy_connect_direct. This sets the phy interface mode to the invalid value, which in turn causes problems for any code using phydev->interface.
