I think we should return an error if asked to set the mode, but its
not implemented by the driver. Something like:

	if (of_property_read_bool(led, "active-low"))
		set_bit(PHY_LED_ACTIVE_LOW, &modes);
	if (of_property_read_bool(led, "inactive-high-impedance"))
		set_bit(PHY_LED_INACTIVE_HIGH_IMPEDANCE, &modes);

		
	if (mode)
		if (phydev->drv->led_polarity_set) {
			return -EINVAL;
		} else {
			err = phydev->drv->led_polarity_set(phydev, index, modes);
			if (err)
				return err;
		}
	}
