ASoC: nau8825: disable crosstalk by default
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: John Hsu KCHSU0@nuvoton.com Date: Fri, 24 Nov 2017 18:08:26 +0800 Subject: [PATCH] ASoC: nau8825: disable crosstalk by default
The driver makes the crosstalk funciton disabled by default which can simplify the codec function. The platform may not need this funciton and reduce the potential risk. Therefore, We change the property "nuvoton,crosstalk-bypass" to "nuvoton,crosstalk-enable". The crosstalk measurement is enabled if the property is set. Otherwise, it is disabled. Besides, add more condition in the entry point of the crosstalk sequence to disable the function completely.
