Description
This issue is spotted on TGLU_UP_HDA/TGLH_SKU0A70_HDA devices, the system freezes in login window. we cannot login even with remote ssh.
After debugging, I block SOF driver, and do manually probe, find that the system hangs on DSP suspend, there is a null pointer de-reference.

@mengdonglin @aiChaoSONG we clearly have gaps in the kernel PR coverage, can we fix this please? we have 5 PRs ready to merge and all tests go boink.

I think (and hope) this is only due to sof-ci.01.org being temporarily down and people being unfamiliar with the internal interface. In other words: no coverage gap that bad.
