[alsa-devel] [PATCH] ASoC: soc.h: use bit field for playback/capture_only

[Kuninori Morimoto]

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

Current snd_soc_dai_link is already using many bit fields.
Let's use it for playback_only/capture_only too.
We can reduce struct size in certain environment.
