[alsa-devel] [PATCH] ASoC: rcar: tidyup simple-card example for CPU node

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

commit a5702e1cb3c ("ASoC: rsnd: Drop unit-addresses without reg
properties") modifies simple-card multi CPU nodes.
But, naming of "cpu-x" breaks probing.
Let's add reg = <x>; instead of renaming node.
