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. This was done using the Coccinelle semantic patch iterators/for_each_child.cocci Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxxx> --- drivers/mmc/host/atmel-mci.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff -u -p a/drivers/mmc/host/atmel-mci.c b/drivers/mmc/host/atmel-mci.c --- a/drivers/mmc/host/atmel-mci.c +++ b/drivers/mmc/host/atmel-mci.c @@ -674,8 +674,10 @@ atmci_of_init(struct platform_device *pd "cd", GPIOD_IN, "cd-gpios"); err = PTR_ERR_OR_ZERO(pdata->slot[slot_id].detect_pin); if (err) { - if (err != -ENOENT) + if (err != -ENOENT) { + of_node_put(cnp); return ERR_PTR(err); + } pdata->slot[slot_id].detect_pin = NULL; } @@ -687,8 +689,10 @@ atmci_of_init(struct platform_device *pd "wp", GPIOD_IN, "wp-gpios"); err = PTR_ERR_OR_ZERO(pdata->slot[slot_id].wp_pin); if (err) { - if (err != -ENOENT) + if (err != -ENOENT) { + of_node_put(cnp); return ERR_PTR(err); + } pdata->slot[slot_id].wp_pin = NULL; } }
