Which is correct in MI2S case. Only replacing dai->id to dai->driver->id should fix the issue on storm board. So I will drop these two changes in next verion. --srini

I think it should be OK to extend that if condition to if (count == 1 && dai_drv[0].id == 0 && legacy_dai_naming) ... It doesn't look like any of the systems for which we currently take the legacy path do set id to non 0. And the less new systems following legacy naming scheme the better. - Lars
