The patch

ASoC: simple-card-utils: separate asoc_simple_card_parse_dai()

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.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks, Mark

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Wed, 20 Mar 2019 13:56:36 +0900 Subject: [PATCH] ASoC: simple-card-utils: separate asoc_simple_card_parse_dai()

The difference between simple-card / audio-graph are just using OF graph style, or not. In other words, other things should be same. This means, simple-card/audio-graph common functions should be implemented at simple-card-utils, and its own functions should be implemented at each files.

Current simple-card / audio-graph are using asoc_simple_card_parse_dai() which is different implementation. But, these are implemanted at simple-card-utils. It should be implemanted at each files. This patch separate these into each files.
