Thanks for this.

 static void __init sio_init(void)
 {
 	struct device_node *root;
+	const char *model = NULL;

You don't need this initialization as you always assign the variable
before you use it.

+	root = of_find_node_by_path("/");
+	if (root) {

	if (!root)
		return;

would save a level of indentation. Not important.
