From 151b8c5ba1eb01bb49efe93bee2dcadb7bfca431 Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Fri, 24 Jun 2016 18:36:30 +0530 Subject: [PATCH] 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 Signed-off-by: Linus Walleij --- drivers/pinctrl/sirf/pinctrl-atlas7.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/pinctrl/sirf/pinctrl-atlas7.c b/drivers/pinctrl/sirf/pinctrl-atlas7.c index 168c0f5d4079..19952f73fa8c 100644 --- a/drivers/pinctrl/sirf/pinctrl-atlas7.c +++ b/drivers/pinctrl/sirf/pinctrl-atlas7.c @@ -5424,8 +5424,10 @@ static int atlas7_pinmux_probe(struct platform_device *pdev) if (ret) return ret; pmx->sys2pci_base = devm_ioremap_resource(&pdev->dev, &res); - if (IS_ERR(pmx->sys2pci_base)) + if (IS_ERR(pmx->sys2pci_base)) { + of_node_put(sys2pci_np); return -ENOMEM; + } pmx->dev = &pdev->dev;
