The patch
ASoC: wm9713: Use core AC'97 reset helper
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: Lars-Peter Clausen lars@metafoo.de Date: Tue, 21 Jul 2015 21:53:06 +0200 Subject: [PATCH] ASoC: wm9713: Use core AC'97 reset helper
Use the new snd_ac97_reset() helper and the reset functionality provided by snd_soc_new_ac97_codec() to perform the device reset rather than open-coding it.
