Asoc: Intel: SST (CHT) regression in asoc/for-5.11

[Hans de Goede]

Hi All,

To test the code to dynamically switch between SST/SOF support on BYT/CHT
from the kernel commandline I merged:

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/log/?h=for-5.11

Into my personal tree (mostly Linus' master + some pending patches from
myself).

After this I was getting the following errors in dmesg when using sound on
a Medion E2228T laptop with a CHT SoC + NAU8824 codec:

Dropping the asoc/for-5.11 merge and just cherry-picking Pierre-Louis' changes
for the dynamic switching makes these go away. So this seems to be caused by
other changes in asoc/for-5.11.

So any clues where to start looking for this, or should I just bisect this?
