Bug description:
[Impact]
the alsa upstream worte the ucm3 files for amd renoir audio, but to
load the ucm3, it depends on the kernel module name, and the upstream
ucm3 needs the name snd-xxx, so we need to backport the patch
from mainline kernel to change the kernel module name to meet ucm3
requirement.
[Fix]
Backport 1 patch from upstream.
[Test Case]
boot the kernel with the patch on amd renoir machines (lenovo
machines), the audio driver works well (via command line like
aplay or areord), then upgrade the alsa-lib and alsa-ucm-conf to
1.2.3.2, now we could see the audio devices from gnome, and they work
well.
[Regression Risk]
Low, this SRU are only specific to soc/amd/renoir, and we already
tested on 2 lenovo machines, their audio worked as before.
