this should be picked together with commit 2aa2a5ead0e ("ASoC: SOF: Intel: 
pci-tgl: unblock S5 entry if DMA stop has failed"), to not bring back old 
bugs (system failures to enter S5 on shutdown). The revert patch 
unfortunately fails to mention this dependency.

If I'm too late with my reply, I can send the second patch separately to 
stable.
