[Mark Brown <broonie@kernel.org>]

The patch

   ASoC: Intel: bytcr_rt5651: Pass jack-src info via device-properties

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.

Subject: [PATCH] ASoC: Intel: bytcr_rt5651: Pass jack-src info via
 device-properties

This commit add support for a new BYT_RT5651_JDSRC quirk, sets this
quirk for the KIANO SlimNote 14.2 laptop and uses the new "realtek,
jack-detect-source" property to pass this info to the codec driver.
