[alsa-devel] Applied "ASoC: soc-core: add new soc_link_init()" to the asoc tree

[Mark Brown]

The patch

   ASoC: soc-core: add new soc_link_init()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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: add new soc_link_init()

Current soc_probe_link_dais() (1) is called under probe_order (2),
and it will initialize dai_link related settings at *Last* turn (3)(B).
It is very complex code.

	static int soc_probe_link_dais(..., order)
	{
(A)		/* probe DAIs here */
		...

(3)		if (order != SND_SOC_COMP_ORDER_LAST)
			return 0;

(B)		/* initialize dai_link related settings */
		...
	}

	static int snd_soc_instantiate_card(...)
	{
		...
(2)		for_each_comp_order(order) {
			for_each_card_rtds(...) {
(1)				ret = soc_probe_link_dais(..., order);
			}
		}
	}

This patch separes soc_probe_link_dais() into "DAI probe" portion (A),
and dai_link settings portion (B).
The later is named as soc_link_init() by this patch.
