[PATCH 0/3] ASoC: remove dai_drv from snd_soc_component

[Kuninori Morimoto]

Hi Mark

These are not important, but cleanup.

snd_soc_component is keeping DAI driver pointer,
but each DAI has its driver, and component has dai_list.
This means, we can reach to all DAI and its driver
by using dai_list. We can remove DAI driver pointer from component.

[PATCH 1/3] ASoC: hdac_hdmi: keep DAI driver pointer in private data

[Kuninori Morimoto]

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

struct snd_soc_component::dai_drv will be removed soon.
hdac_hdmi is only user of it. Let's keep it on private data.

[PATCH 2/3] ASoC: soc-core: remove dai_drv from snd_soc_component

[Kuninori Morimoto]

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

ALSA SoC has some duplicate parameter.
snd_soc_component::dai_drv is one of them.

Each DAI is keeping its driver as snd_soc_dai::driver,
and component has dai_list.
This means, we can reach to each DAI and its driver by using dai_link.
Thus, there is no need to keep DAI driver pointer on component.
Let's remove it

Applied "ASoC: soc.h: Arrange DAI related parameter" to the asoc tree

[Mark Brown]

The patch

   ASoC: soc.h: Arrange DAI related parameter

has been applied to the asoc tree at

   https://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
