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.
The semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root,e; local idexpression child; @@ for_each_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.law...@lip6.fr> --- drivers/regulator/of_regulator.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/regulator/of_regulator.c b/drivers/regulator/of_regulator.c index 499e437..f9d77b4 100644 --- a/drivers/regulator/of_regulator.c +++ b/drivers/regulator/of_regulator.c @@ -274,6 +274,7 @@ int of_regulator_match(struct device *dev, struct device_node *node, dev_err(dev, "failed to parse DT for regulator %s\n", child->name); + of_node_put(child); return -EINVAL; } match->of_node = of_node_get(child); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
