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

There is also an extra of_node_put() before a continue in the same
loop on line 1001 of this file which should be deleted. Julia Lawall has
already sent a patch to delete this but if preferred I can send one patch
to do both the changes.
