There should be an of_node_put when breaking out of a loop that iterates
using for_each_node_by_type.
This was detected and fixed using the following semantic patch.
(http://www.emn.fr/x-info/coccinelle/)

identifier d;
type T;
expression e;
iterator for_each_node_by_type;

{... when != of_node_put(d)
when != e = d
(
return d;

+ of_node_put(d);
? return ...;
)
...}
