Call the rt2x00lib_get_eeprom_file_name only once and from the function where the EEPROM filename is required. Error only out if an EEPROM file is mandatory. Use the REQUIRE_EEPROM_FILE bit to determine if it is mandatory. Do not set the REQUIRE_EEPROM_FILE bit while requesting an EEPROM file. It should be (and is) set before requesting an EEPROM file. Do not redirect users to upstream while using a function of a custom patch. Signed-off-by: Mathias Kresin <dev@kresin.me>
