From 9dec58e6c4d44175eaab64308c1bc27a2b5cb555 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 12 Oct 2015 22:43:14 +0200 Subject: [PATCH] video: omapdss: delete unneeded of_node_put Device node iterators perform an of_node_put on each iteration, so putting an of_node_put before a continue results in a double put. A simplified version of the semantic match that finds this problem is as follows (http://coccinelle.lip6.fr): // @@ expression root,e; local idexpression child; iterator i; @@ i(..., child, ...) { ... when != of_node_get(child) * of_node_put(child); ... * continue; } // Signed-off-by: Julia Lawall Signed-off-by: Tomi Valkeinen --- drivers/video/fbdev/omap2/dss/omapdss-boot-init.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/drivers/video/fbdev/omap2/dss/omapdss-boot-init.c b/drivers/video/fbdev/omap2/dss/omapdss-boot-init.c index 8b6f6d5fdd68..136d30484d02 100644 --- a/drivers/video/fbdev/omap2/dss/omapdss-boot-init.c +++ b/drivers/video/fbdev/omap2/dss/omapdss-boot-init.c @@ -199,10 +199,8 @@ static int __init omapdss_boot_init(void) omapdss_walk_device(dss, true); for_each_available_child_of_node(dss, child) { - if (!of_find_property(child, "compatible", NULL)) { - of_node_put(child); + if (!of_find_property(child, "compatible", NULL)) continue; - } omapdss_walk_device(child, true); } -- 2.39.2
