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

[Mark Brown]

The patch

   ASoC: soc-core: tidyup soc_init_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: tidyup soc_init_dai_link()

soc_init_dai_link() is needed to be called before soc_bind_dai_link().

	int snd_soc_instantiate_card()
	{
		for_each_card_prelinks(...) {
(1)			ret = soc_init_dai_link(...);
			...
		}
		...
		for_each_card_prelinks(...) {
(2)			ret = soc_bind_dai_link(...);
			...
		}
		...
		for_each_card_links(...) {
			...
(A)			ret = soc_init_dai_link(...);
			...
(B)			ret = soc_bind_dai_link(...);
		}
		...

(1) is for (2), and (A) is for (B)
(1) and (2) are for card prelink   dai_link.
(A) and (B) are for topology added dai_link.

soc_init_dai_link() is sanity check for dai_link, not initializing today.
Therefore, it is confusable naming. We can rename it as sanity_check.

And this check is for soc_bind_dai_link().
It can be more simple code if we can call it from soc_bind_dai_link().

This patch renames it to soc_dai_link_sanity_check(), and
call it from soc_bind_dai_link().
