The MSI Crosshair A16 HX D7WFKG has an internal digital microphone
connected through AMD ACP6x, but the system does not expose the
AcpDmicConnected ACPI property. As a result, acp_yc_mach does not bind
and no DMIC capture device is created.

Add a DMI quirk for this model. This was tested on a system with board
MS-15PL, BIOS E15PLAMS.10B, and AMD ACP6x rev 0x62. After applying the
quirk, the internal microphone appears as an acp6x DMIC capture device
and records correctly.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-7.2

Thanks!

[1/1] ASoC: amd: yc: Add MSI Crosshair A16 HX D7WFKG to quirk table
      https://git.kernel.org/broonie/sound/c/f7074624bafc

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
