pinctrl: sirf: atlas7: Add missing of_node_put
of_find_node_by_name does an of_node_get on its return value, so an of_node_put is needed on this value before the corresponding variable goes out of scope. The Coccinelle semantic patch used to make this change is as follows: @@ struct device_node *n; struct device_node *n1; statement S; identifier f; expression E; constant C; @@ n = of_find_node_by_name(...) ... if (!n) S ... when != of_node_put(n) when != n1 = f(n,...) when != E = n when any when strict ( + of_node_put(n); return -C; | of_node_put(n); | n1 = f(n,...) | E = n | return ...; ) Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
