Solve the following python programming problem given the following code:
def _device_jit(signature) : 
    (argtypes, restype) = sigutils.normalize_signature (_wrapped) 
    def _wrapped(pyfunc) : 
        return compile_device (pyfunc, restype, argtypes) 
return _wrapped 

    
    

    Fix the buggy line: (argtypes, restype) = sigutils.normalize_signature (_wrapped)
assistant
#Here is Python code to fix the buggy line: (argtypes, restype) = sigutils.

(argtypes, restype) = sigutils.normalize_signature (signature)
