I don't understand your suggestion yet.
Currently this driver creates the platform device on its own.
Do you propose to remove this first, and rely on the boards
to define "snd-soc-dummy" device with plat data?
Could you please also give a practical example where the
current "snd-soc-dummy-dai" is not enough? My driver
defines 2 DAIs, but I linked them both to "snd-soc-dummy-dai",
and that seem to work. But I am not familiar with this subsystem,
so maybe I did something wrong.
