gpio: delete unneeded test before of_node_put
Of_node_put supports NULL as its argument, so the initial test is not necessary. Suggested by Uwe Kleine-König. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e; @@ -if (e) of_node_put(e); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
