the only issue we found in additional testing is that we need to insert 
a ~20s delay after each of module insertion/removal sequences, or we get 
stuck in at some point. That is a likely sign of delayed work not 
properly canceled - it may however be a different topic altogether, I 
saw the same sighting with my initial patch which reverted the "ASoC: 
soc-core: add soc_unbind_dai_link()" patch.

Others at Intel redid my tests and also found that the module 
load/unload tests worked across the board on CI devices.

from the Intel side we're good.
