Solve the following python programming problem given the following code:
def _instrument_runner(runner_generator, logger, runner) : 
    method_name = _get_make_result_method_name (runner_generator) 
    old_make_result = getattr (runner, method_name) 
    runner.logger = logger 
    def _instrumented_make_result(self) : 
        result = old_make_result () 
        return _instrument_result (logger, result) 
setattr (runner, method_name, MethodType (old_make_result, runner)) 
    return runner 

    
    

    Fix the buggy line: setattr (runner, method_name, MethodType (old_make_result, runner))
