I sent a similar patch to Russell for the clk API and he rightfully NAKed it. NULL is a valid cookie from clk_get and the whole clk API is able to deal with NULL. That ensures that for !HAVE_CLK, clk_get is still successful and won't fail driver_probe while the other clk API functions don't really do anything. If the gpio API is similar to that, we should revert my patch. Sorry for the nuisance, Wolfram
