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. A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root,e; local idexpression child; @@ for_each_available_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> --- drivers/leds/leds-bcm6328.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/leds/leds-bcm6328.c b/drivers/leds/leds-bcm6328.c index 18de094..c7ea5c6 100644 --- a/drivers/leds/leds-bcm6328.c +++ b/drivers/leds/leds-bcm6328.c @@ -403,8 +403,10 @@ static int bcm6328_leds_probe(struct platform_device *pdev) rc = bcm6328_led(dev, child, reg, mem, lock, blink_leds, blink_delay); - if (rc < 0) + if (rc < 0) { + of_node_put(child); return rc; + } } return 0; -- 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
