for_each_child_of_node performs an of_node_get on each iteration, so to break out of the loop an of_node_put is required. Found using Coccinelle. The semantic patch used for this is as follows: // <smpl> @@ expression e; local idexpression n; @@ for_each_child_of_node(..., n) { ... when != of_node_put(n) when != e = n ( return n; | + of_node_put(n); ? return ...; ) ... } // </smpl Signed-off-by: Amitoj Kaur Chawla <amitoj1606@xxxxxxxxx> --- drivers/of/resolver.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/of/resolver.c b/drivers/of/resolver.c index 640eb4c..e2a0143 100644 --- a/drivers/of/resolver.c +++ b/drivers/of/resolver.c @@ -40,8 +40,10 @@ static struct device_node *__of_find_node_by_full_name(struct device_node *node, for_each_child_of_node(node, child) { found = __of_find_node_by_full_name(child, full_name); - if (found != NULL) + if (found != NULL) { + of_node_put(child); return found; + } } return NULL; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
