Bug description:
The fix is already in the upstream kernel v5.19-rc1, no need to
send the patches to unstable kernel. And for Jammy kernel, this SRU
depends on #1949245, after merging the patchset for #1949245, then
could apply this SRU to jammy.
[Impact]
On the AMD YC platforms, the internal mic can't be detected
and there is no internal mic for users to use.
[Fix]
Backport 2 patches from mainline kernel to fix this problem.
[Test]
boot the patched kernel on the machine which has updated BIOS, after
loging into the desktop, open the gnome-sound-setting, there is
internal mic, and could record sound via internal mic.
[Where problems could occur]
This only impacts intenal mic detection on AMD yc machines, it will
check the acpi variable first, if not detected, it will check the acpi
dmi table as before, so the regression possibility is very low, and we
already tested these patches on a couple of Lenovo YC machines, all
worked well.
