Solve the following python programming problem given the following code:
def _test_timer_decorator(cl, proto) : 
    @ cl.timer ('foo') 
    def foo(a, b) : 
        return [a, b] 
@ cl.timer ('bar') 
    def bar(a, b) : 
        return [b, a] 
eq_ ([4, 2], foo (4, 2)) 
    _timer_check (cl._sock, 1, cl, 'foo', 'ms') 
    eq_ ([2, 4], bar (4, 2)) 
    _timer_check (cl._sock, 2, proto, 'bar', 'ms') 
    eq_ ([6, 5], bar (5, 6)) 
    _timer_check (cl._sock, 3, proto, 'bar', 'ms') 

    
    

    Fix the buggy line: _timer_check (cl._sock, 1, cl, 'foo', 'ms')
