Bug Description
This patchset is already in the upstream kernel-5.6, so no need to
send for unstable.
And this patchset will remove an existing kernel module and add a new
kernel module, so need to change the ABI/modules.ignore manually.
The module removed: snd-intel-nhlt.ko
The module added: snd-intel-dspcfg.ko
[Impact]
There is already dmic detection code in the eoan and focal kernel, it
works well on CNL/WHL and later Intel platforms, but it doesn't work
on KBL, SKL and old Intel machines.
https:/
[Fix]
The upstream kernel updated the dmic detection code, it will exclude the
old intel machines by default. Then the old machines will use legacy hda
driver like before.
[Test Case]
Install the testing kernel to Dell/LENOVO WHL/CNL and later machines,
they work as well as before.
And a user verifed the testing kernel work on his KBL machine.
https:/
[Regression Risk]
Low, those patches come from mainline kernel, I have tested those patches
on the WHL/CNL and later machiens, a user tested it on a KBL machine.
