That message is printed when no connector node is linked in DT through OF 
graph to the encoder DT node output port. That's expected in this case as we 
have an LVDS encoder, but not connected panel. However, 
rcar_du_encoders_init_one() should return before printing that message due to

        if (!of_device_is_available(entity)) {
                dev_dbg(rcdu->dev,
                        "connected entity %pOF is disabled, skipping\n",
                        entity);
                return -ENODEV;
        }

as the LVDS encoder nodes in DT should be disabled.
