[PATCH 1/8] ASoC: soc-pcm: use defined stream

[Kuninori Morimoto]

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

Many functions defines "stream = substream->stream", but
some of them is using "substream->stream" instead of "stream".
It is pointless. This patch uses defined stream.
