The Lenovo Yoga Pro 7 14ASP9 (83HN) has no digital microphone on the ACP
PDM interface; all internal mics are wired to the Realtek ALC287 codec.
Add 83HN to acp70_acpi_flag_override_table to prevent the legacy ACP
driver from binding and exposing a non-functional PDM capture device,
consistent with the sibling 83W5/83V9 entries.

Applied to

Thanks!

[1/1] ASoC: amd: acp: Add DMI quirk for Lenovo Yoga Pro 7 14ASP9
      https://git.kernel.org/broonie/sound/c/5d35f9be9b54

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

This is good, but does show that we have what looks like a quirk in the
wrong driver from a28206060dc58 (ASoC: amd: yc: Add quirk for Lenovo
Yoga Pro 7 14ASP9), unless they reused a name or something.
