Subject: [PATCH 4/5] ASoC: intel: sst-mfld-platform-pcm: add .delay support
Date: 16 Nov 2021 16:45:29 +0900 [thread overview]
Message-ID: <871r3gy25j.wl-kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <877dd8y26l.wl-kuninori.morimoto.gx@renesas.com>
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
Now ALSA SoC supports .delay for component.
This patch uses it, and not update runtime->delay on .pointer
directly / secretly.
