[ Test ]
1. Test record/playback of built-in mic and speakers by, say, recording and
playing the speaker test sound in the gnome control center.
2. Connect to headphones and test playback and recording.
3. Suspend the machine and test 1. and 2. again.
4. Test the above 3 on a ACP63 machine.
[ Where the problems could occur ]
Most of the codes are AMD-specific. However, those patches contain
refactors to the existing ACP63 codes. Errors in those refactoring may
impact existing ACP63 platforms.
The patch "[PATCH V3 19/25] ASoC: amd: ps: update file description and
copyright year"[3] didn't get backported, because it conflicted due to
the recent MODULE_IMPORT_NS() API change in cdd30ebb1b9f (module:
Convert symbol namespace to string literal). This patch only change
the module description and doesn't have real functional impact, so was
not pulled in.
