Are you sure? I just randomly checked one caller to see what the
*eeprom_mac_addr would contain, and I see

        mac = rt2x00_eeprom_addr(rt2x00dev, EEPROM_MAC_ADDR_0);
        rt2x00lib_set_mac_address(rt2x00dev, mac);

so that case assumes it can get it from EEPROM and override with OF, but
if OF fails then it would still use the EEPROM address as long as it's
valid ...
