[1/1] ASoC: amd: yc: Add quirk for HP 200 G2a 16
      commit: 611c7d2262d5645118e0b3a9a88475d35a8366f2

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

Is this a production hardware and firmware?

If so this patch makes sense.

If it's not, can you please explore adding the _DSD entry 
"AcpDmicConnected".
