Julia Lawall 56e5c527cc drm/of: free the right object 
[ Upstream commit b557a5f8da ]

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>
