The HP Laptop 15-fc0xxx (subsystem ID 0x103c8dc9) has an internal
DMIC connected to the AMD ACP6x audio coprocessor. Add a DMI quirk
entry so the internal microphone is properly detected on this model.

Tested on HP Laptop 15-fc0237ns with Fedora 43 (kernel 6.19.9).

[1/1] ASoC: amd: yc: Add DMI entry for HP Laptop 15-fc0xxx
      https://git.kernel.org/broonie/sound/c/8ec017cf3129

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
