[alsa-devel] [PATCH 1/3] rcar: ctu: Avoid use of ret uninitialised

[Mark Brown]

We use ret as the return value from the rsnd_ctu_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.

Perhaps this should be an error instead?  It's not like it's a sensible
configuration...
