Will send v2 with a better explanation.

Not sure I follow your question. I think the difference stands in the
way we treat OF vs non-OF platforms.

With OF-platforms, dai_link->platforms->of_node is always set! So we
no longer need
to set dai->platforms->name.

Actually setting both of_node and name will make sound card
registration fail! In this is the case I'm trying
to fix here.
