The patch
ASoC: add Component level set_sysclk
has been applied to the asoc tree at
git://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: Thu, 24 Aug 2017 00:57:35 +0000 Subject: [PATCH] ASoC: add Component level set_sysclk
In current ALSA SoC, Codec only has set_sysclk feature. Codec will be merged into Component in next generation ALSA SoC, thus current Codec specific feature need to be merged into it. This is glue patch for it.
