of_get_child_by_name() takes a reference to an OF node, you must release
it in the error path.

+	inst_modpriv = devm_kzalloc(dev, sizeof(*inst_modpriv), GFP_KERNEL);
+	if (!inst_modpriv) {
+		dev_err(dev, "Failed to allocate instance for %s\n",
+			module->name);
+		return -ENOMEM;
+	}

Likewise, but here you have to release both "devices" and "child".

You're going to have to fix this OF node refcount problem for this
entire probe routine.
