This patchset does not modify this behaviour. It simply fixes the
stall for kexec().

The  patch that introduced the stall:
83bfc7e793b5 ("ASoC: SOF: core: unregister clients and machine drivers
in .shutdown")

That patch is problematic. I would go as far as saying that
it needs to be reverted.

It fixes a real issue. We have not had any complaints until we tried
to kexec in the platform.
I wont recommend reverting it until we have an alternative implementation.

kexec is far less common than suspend/reboot.

I've posted an alternative to ALSA list that reverts the problematic
patch and fixes the problem (the patch was originally addressing)
in a different way:

https://mailman.alsa-project.org/pipermail/alsa-devel/2022-December/209776.html

No changes outside sound/soc/ are needed with this approach.
