The patch
ASoC: simple-card: support snd_soc_dai_link_component style for codec
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.

Current ASoC is supporting snd_soc_dai_link_component for binding, it is more useful than current legacy style. Currently only codec is supporting it as multicodec (= codecs). CPU will support multi style in the future. We want to have it on Platform too in the future.
If all Codec/CPU/Platform are replaced into snd_soc_dai_link_component style, we can remove legacy complex style. This patch supports snd_soc_dai_link_component style for simple-card for codec.
[current] struct snd_soc_dai_link { ... *cpu_name; *cpu_of_node; *cpu_dai_name;
*codec_name; *codec_of_node; *codec_dai_name; *codecs; num_codecs;
*platform_name; *platform_of_node; ... }
[in the future] struct snd_soc_dai_link { ... *cpus num_cpus;
*codecs; num_codecs;
*platform; ... }
