Indeed, and I tested a change like that here:

	https://lore.kernel.org/lkml/ZIHSGf18Aw7htb9o8@hovoldconsulting.com/

but that only seems to make the problem worse currently.

This should probably still be fixed, but I was just hoping that the DAI
numbering could have been the cause for the probe deferral (which then
triggers the other bugs).
