Subject: [alsa-devel] [PATCH v2 02/15] ASoC: soc-core: remove snd_soc_disconnect_sync()
Date: 25 Nov 2019 09:43:35 +0900 [thread overview]
Message-ID: <874kysg4zs.wl-kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <877e3og50x.wl-kuninori.morimoto.gx@renesas.com>
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
Sound card disconnecting operation was needed when "sound driver" was
unbinded without unbinding "sound card".
In such case, sound driver should be stopped even though it was
playbacking/capturing. Otherwise clock open/close counter mismatch happen.
One headache was that we can't skip unbind in error case because unbind
operation doesn't check return value from each drivers.
snd_soc_disconnect_sync() was added for these purpose, and Renesas
sound card only is used it.
But now, ALSA SoC automatically disconnect sound card when sound driver
was unbinded. Thus, snd_soc_disconnect_sync() is no longer needed.
This patch removes it.
