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> @@ local idexpression r.n; expression r,e; @@ for_each_available_child_of_node(r,n) { ...
