[PATCH] ASoC: amd: yc: Add Alienware m15 R7 AMD to DMIC quirk table

[Jetha Chan]

The Alienware m15 R7 AMD exposes an ACP6x DMIC path, but its DMI
product name is not present in the Yellow Carp ACP quirk table. As a
result, the ACP machine driver does not enable the DMIC card on this
system.

Add the DMI product name for this machine. With this quirk applied, the
kernel reports:

  acp_yc_mach acp_yc_mach.0: Enabling ACP DMIC support via DMI

and ALSA exposes the ACP DMIC capture device:

  card 3: acp6x
  device 0: DMIC capture dmic-hifi-0

Tested on an Alienware m15 R7 AMD with product SKU 0B59.

Applied to

Thanks!

[1/1] ASoC: amd: yc: Add Alienware m15 R7 AMD to DMIC quirk table
      https://git.kernel.org/broonie/sound/c/e782d687d2f5

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
