From 6cc7624415466022749a868c159ac68367bc9a0e Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 24 Oct 2015 16:42:29 +0200 Subject: leds: bcm6328: add missing of_node_put 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): // @@ 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 ...; ) ... } // Signed-off-by: Julia Lawall Signed-off-by: Jacek Anaszewski --- drivers/leds/leds-bcm6328.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'drivers/leds') diff --git a/drivers/leds/leds-bcm6328.c b/drivers/leds/leds-bcm6328.c index 18de0942c795..c7ea5c626331 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; -- cgit v1.2.3-59-g8ed1b
