| |
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>
