| |
From: Julia Lawall <Julia.Lawall@lip6.fr>
Of_node_put supports NULL as its argument, so the initial test is not necessary.
Suggested by Uwe Kleine-König.
The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @@ expression e; @@
-if (e) of_node_put(e); // </smpl>
