| |
The device node iterators perform an of_node_get on each iteration, so a jump 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; iterator name for_each_child_of_node; @@
for_each_child_of_node(root, child) { ... when != of_node_put(child) when != e = child + of_node_put(child); ? break; ... } ... when != child // </smpl>
