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;
}
}
