The patch
ASoC: codecs: ak4104: move to GPIO consumer API
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: Daniel Mack daniel@zonque.org Date: Thu, 6 Dec 2018 13:24:57 +0100 Subject: [PATCH] ASoC: codecs: ak4104: move to GPIO consumer API
Get the reset GPIO through the GPIO consumer API. This allows specifying the DT property as "reset-gpios" without breaking existing DT users.
