for_each_available_child_of_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. This was done using the Coccinelle semantic patch iterators/for_each_child.cocci Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxxx> --- drivers/soc/dove/pmu.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff -u -p a/drivers/soc/dove/pmu.c b/drivers/soc/dove/pmu.c --- a/drivers/soc/dove/pmu.c +++ b/drivers/soc/dove/pmu.c @@ -410,13 +410,16 @@ int __init dove_init_pmu(void) struct pmu_domain *domain; domain = kzalloc(sizeof(*domain), GFP_KERNEL); - if (!domain) + if (!domain) { + of_node_put(np); break; + } domain->pmu = pmu; domain->base.name = kasprintf(GFP_KERNEL, "%pOFn", np); if (!domain->base.name) { kfree(domain); + of_node_put(np); break; }
