In case there is no DAI (yet), do not print an error, this might happen a lot of times. Print a notice instead.
Oh, and the other thing about this which I should have mentioned is that it applies to every single resource acquisition in the kernel - this needs addressing at a global error rather than piecemeal. Raphael was intending to work on avoiding probe deferral in the first place by sorting probe and there were also some proposals to have a helper for printing error messages which would suppress the display of probe deferral errors before the final run at late initcall. Obviously the second mechanism is substantially simpler to implement.
I remember those patches a bit. But working with late initcall sound to me this has no effect on probe deferral in drivers loaded by modules, no?
