--- Comment #3 from Direx <direx at betriebsdirektor.de> ---
I have tried your patch against drm-intel-nightly, but unfortunately it does
not fix the issue. The PCI id of my card is correct, though:

00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-LP HD Audio
[8086:9d70] (rev 21)

I can now also describe how to reproduce the issue (it is unrelated to
suspend):

1. Boot system normally

2. Play back any sound

3. Run `powertop` and apply all "optimizations" (I think the
`snd_hda_intel.power_save` optimization is not enough)

4. Wait for a few seconds

5. Play back any sound -> the warning message appears in the system log

BTW: The register involved in this is always 0x65f10
