Is this variable still needed at all? Looks like it's a remnant after a1f4971863 that can now only return 0 or 2 so you could just remove this variable and return 2 where now it's assigned as 2 or change return olen at the end to return 2 or maybe keep olen and change the return 0 above to return olen to silence warning but I think this could be cleaned up.
