[alsa-devel] [PATCH 3/3] rcar: mux: Avoid use of ret uninitialised

We use ret as the return value from the rsnd_mix_probe() but if there are no child nodes and no errors then we will never initialize ret leading to build warnings. Ensure ret is initialized before we iterate over the child nodes to avoid this.
