for_each_child_of_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. The semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root,e; local idexpression child; @@ for_each_child_of_node(root, child) { ... when != of_node_put(child) when != e = child ( return child; | + of_node_put(child); ? return ...; ) ... } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- arch/arm/mach-shmobile/pm-rmobile.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-shmobile/pm-rmobile.c b/arch/arm/mach-shmobile/pm-rmobile.c index 89068c8..46d0a1d 100644 --- a/arch/arm/mach-shmobile/pm-rmobile.c +++ b/arch/arm/mach-shmobile/pm-rmobile.c @@ -313,8 +313,10 @@ static int __init rmobile_add_pm_domains(void __iomem *base, } pd = kzalloc(sizeof(*pd), GFP_KERNEL); - if (!pd) + if (!pd) { + of_node_put(np); return -ENOMEM; + } pd->genpd.name = np->name; pd->base = base; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
