Solve the following python programming problem given the following code:
def _get_c_types(self) : 
    def m(t) : 
        if (t == gpuarray.GpuArray) : 
            return 'GA_BUFFER' 
else : 
            return str (gpuarray.dtype_to_typecode (t)) 
return ', '.join ((m (t) for t in t.params)) 

    
    

    Fix the buggy line: return ', '.join ((m (t) for t in t.params))
