The patch

   ASoC: Intel: bytcr_rt5651: Add BYT_RT5651_HP_LR_SWAPPED quirk

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

Subject: [PATCH] ASoC: Intel: bytcr_rt5651: Add BYT_RT5651_HP_LR_SWAPPED quirk

One some models (Chuwi Vi8 Plus, Chuwi Hi8 Pro) the headphone output has
left and right swapped. This can be fixed in with special mixer settings
in the UCM profile, bit this requires these devices loading a different
UCM profile.

This commit adds a BYT_RT5651_HP_LR_SWAPPED quirk for this and postfixes
the longname with "-hp-swapped" if set, so that a different UCM profile
will be loaded.

We can safely do this without causing regressions (UCM profile not found
due to the longname change) as the UCM profiles are not in upstream
alsa-lib yet.
