[alsa-devel] [PATCH 1/3] ASoC: simple-card-utils: don't select unnecessary Platform

[Kuninori Morimoto]

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

ALSA SoC is now supporting "no Platform". Sound card doesn't need to
select "CPU component" as "Platform" anymore if it doesn't need
special Platform.
This patch removes such settings.
