We're already finding warnings on all Intel SoundWire platforms:

The DAIs are declared as supporting playback AND capture, but in
practice they can only support one direction at a time.

The direction is defined by the dailink when it includes specific DAIs.

So if you don't mind I'd prefer it if we shared a patch with you to be
included in a v5, to make sure at least the Intel platforms tested in CI
are all ok from Day1, otherwise we're going to get lots of noise
reported for no good reason.
Shouldn't take long.
