This patch did not seem to fix the problem. The following code did seem to
fix the problem:

	if (!of_node && dev->parent->of_node)
-               of_node = dev->parent->of_node;
+       do {
+               of_node = dev->of_node;
+               dev = dev->parent;
+               i++;
+       } while (!of_node && dev);
