None of the implementations of the get() and get_hw() callbacks of "struct of_clk_provider" modify the contents of received of_phandle_args pointer. They treat it as read-only variable used to find the clock to return. Make obvious that implementations are not supposed to modify the of_phandle_args, by making it a pointer to const.
