Nope, you don't.
rc = of_property_read_u8(of_node, led, &led_mode);
If rc indicates an error, led_mode is not touched. Read the
documentation for this function. So you can simplifiy the code:
led_mode = default_mode;
err = of_property_read_u8(of_node, led, &led_mode);
if (!err && (led_mode > 15 || led_mode == 7) | (led_mode == 11) {
phydev_err(phydev, "DT %s invalid\n", led);
return -EINVAL;
}
return led_mode;
