From 4b6ba5e28b2903fa8b51c6d5fdafb2979fe6eeab Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 24 Oct 2015 16:42:28 +0200 Subject: leds: bcm6358: 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-bcm6358.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'drivers/leds/leds-bcm6358.c') diff --git a/drivers/leds/leds-bcm6358.c b/drivers/leds/leds-bcm6358.c index 7ea3526702e0..82b4ee1bc87e 100644 --- a/drivers/leds/leds-bcm6358.c +++ b/drivers/leds/leds-bcm6358.c @@ -215,8 +215,10 @@ static int bcm6358_leds_probe(struct platform_device *pdev) } rc = bcm6358_led(dev, child, reg, mem, lock); - if (rc < 0) + if (rc < 0) { + of_node_put(child); return rc; + } } return 0; -- cgit v1.2.3
