| |
for_each_compatible_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> @@ local idexpression n; expression e; @@
for_each_compatible_node(n,...) { ... ( of_node_put(n); | e = n | + of_node_put(n); ? break; ) ... } ... when != n // </smpl>
