From 30645307e5d2c8a4caf978558c66121ac91ad17e Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 23 Feb 2019 14:20:42 +0100 Subject: ARM: OMAP2+: add missing of_node_put after of_device_is_available Add an of_node_put when a tested device node is not available. The semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // @@ identifier f; local idexpression e; expression x; @@ e = f(...); ... when != of_node_put(e) when != x = e when != e = x when any if (<+...of_device_is_available(e)...+>) { ... when != of_node_put(e) ( return e; | + of_node_put(e); return ...; ) } // Fixes: e0c827aca0730 ("drm/omap: Populate DSS children in omapdss driver") Signed-off-by: Julia Lawall Signed-off-by: Tony Lindgren --- arch/arm/mach-omap2/display.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-omap2/display.c b/arch/arm/mach-omap2/display.c index 1444b4b4bd9f..439e143cad7b 100644 --- a/arch/arm/mach-omap2/display.c +++ b/arch/arm/mach-omap2/display.c @@ -250,8 +250,10 @@ static int __init omapdss_init_of(void) if (!node) return 0; - if (!of_device_is_available(node)) + if (!of_device_is_available(node)) { + of_node_put(node); return 0; + } pdev = of_find_device_by_node(node); -- cgit v1.2.3
