The patch
ASoC: soc-core: support snd_soc_dai_link_component for aux_dev
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.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 8 Aug 2019 14:52:33 +0900 Subject: [PATCH] ASoC: soc-core: support snd_soc_dai_link_component for aux_dev
To find aux_dev, ASoC is using .name, codec_name, codec_of_node. Here, .name is used to fallback in case of no codec.
But, we already have this kind of component finding method by snd_soc_dai_link_component and soc_find_component(). We shouldn't have duplicated implementation to do same things. This patch adds snd_soc_dai_link_component support to finding aux_dev.
Now, no driver is using only .name. All drivers are using codec_name and/or codec_of_node. This means no driver is finding component from .name so far. (Actually almost all drivers are using .name as just "device name", not for finding component...)
This patch 1) add snd_soc_dai_link_component support for aux_dev. legacy style will be removed if all drivers are switched to new style. 2) try to find component via snd_soc_dai_link_component. Then, it doesn't try to find via .name, because no driver is using it so far.
