| H A D | drm_of.c | b557a5f8 Fri Jul 09 15:07:17 CDT 2021 Julia Lawall <Julia.Lawall@inria.fr> drm/of: free the right object
There is no need to free a NULL value. Instead, free the object
that is leaking due to the iterator.
The semantic patch that finds this problem is as follows:
// <smpl>
@@
expression x,e;
identifier f;
@@
x = f(...);
if (x == NULL) {
... when any
when != x = e
* of_node_put(x);
...
}
// </smpl>
