[PATCH v2] ASoC: AMD Renoir - add DMI entry for Lenovo ThinkPad E14 Gen 2

[PATCH v2] ASoC: AMD Renoir - add DMI entry for Lenovo ThinkPad E14 Gen 2

[Jaroslav Kysela]

The ThinkPad E14 Gen 2 latop does not have the internal digital
microphone connected to the AMD's ACP bridge, but it's advertised
via BIOS. The internal microphone is connected to the HDA codec.

Use DMI to block the microphone PCM device for this platform.

[1/1] ASoC: AMD Renoir - add DMI entry for Lenovo ThinkPad E14 Gen 2
      commit: 275565997ade6fc32be9cd49a910ba996bcb4797

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
