Yeah, simplification comes only if a driver is checking the return value
what most are not doing currently.

Another issue that came to my mind if some drivers need to add
additional interconnects later then there's basically need to revert
the 4/4 for those codecs. However, I don't think there are many codecs
that will do that.
