[alsa-devel] Applied "ASoC: soc-core: merge snd_soc_add_dai_link() and soc_bind_dai_link()" to the asoc tree

[Mark Brown]

The patch

   ASoC: soc-core: merge snd_soc_add_dai_link() and soc_bind_dai_link()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5

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: merge snd_soc_add_dai_link() and
 soc_bind_dai_link()

We don't need to separete snd_soc_add_dai_link() and
soc_bind_dai_link() anymore. Let's merge these.

One note is that before this patch, it adds list (A)
eventhough if it had dai_link->ignore (1), or already bounded dai_link (2).
But I guess it is wrong. This patch also solve this issue.

/* BEFORE */
	int soc_bind_dai_link(...)
	{
		...
(1)		if (dai_link->ignore)
			return 0;

(2)		if (soc_is_dai_link_bound(...))
			return 0;
		...
	}

	int snd_soc_add_dai_link(...)
	{
		...
=>		ret = soc_bind_dai_link(...);
=>		if (ret < 0)
=>			return ret;

(A)		list_add_tail(&dai_link->list, &card->dai_link_list);
		...
	}

/* AFTER */

	int snd_soc_add_dai_link(...)
	{
		...
(1)		if (dai_link->ignore)
			return 0;

(2)		if (soc_is_dai_link_bound(...))
			return 0;
		...
(A)		list_add_tail(&dai_link->list, &card->dai_link_list);
		return 0;
	}
