So we need to split these into three separate problems:

- Prefixing
- DAPM linking between codecs
- Registering DAIless codecs in machine drivers

What you think: is it better to hold my prefixing patch until DAPM
linking is solved or can it be applied before? I mean if we need to go
some global, not codec based DAPM, then there is need to prefix but not
if DAPM remains per codec.
