-ENODEV is interpreted by the generic driver probing function as a non-matching driver. This leads to a missing probe failure message. Also a missing USB PHY is more of an invalid configuration of the usb driver because it is necessary. This patch returns -EINVAL if devm_usb_get_phy_by_phandle() returned -ENODEV.
