[alsa-devel] Applied "ASoC: rsnd: rsnd_dai_stream has each mod's status insted of rsnd_mod" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: rsnd_dai_stream has each mod's status insted of rsnd_mod

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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: rsnd: rsnd_dai_stream has each mod's status insted of
 rsnd_mod

Renesas sound needs many devices
(SSI/SSIU/SRC/CTU/MIX/DVC/CMD/AudioDMAC/AudioDMACpp).
SSI/SRC/CTU/MIX/DVC are implemented as module.
SSI parent, SSIU are implemented as part of SSI
CMD is implemented as part of CTU/MIX/DVC
AudioDMAC/AudioDMACpp are implemented as part of SSI/SRC
It is nice sense that these all devices are implemented as mod.

Current rsnd is controling each mod's status on mod. But it was not
good design for SSI, because stream might has SSI-parent.
In such case, it can't play/capture in same time, because SSI-parent
is used as normal SSI in other stream, but it shares same status.
To avoid this issue each mod's status is controlled by rsnd_dai_stream
instead of rsnd_mod.
