[alsa-devel] Applied "ASoC: soc-core: remove snd_soc_disconnect_sync()" to the asoc tree

[Mark Brown]

The patch

   ASoC: soc-core: remove snd_soc_disconnect_sync()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: soc-core: remove snd_soc_disconnect_sync()

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.
