I also don't see any case where we support 4 channels in any broadwell
machine driver?
It's the bdw-rt5650.c which only exists in chrome's 3.14 branch supporting Buddy
project. They submitted the machine driver but not yet merged.

Humm, can you clarify what problem/error this patch fixes?
There are already constraints on the hsw_dais[] where the channels are
