This is the way Liam's Haswell DPCM driver works.

A new CPU DAI will be a front end DAI.  So what you're saying here is
that your earlier statement where you clearly said "one front end and
two back ends" was wrong.

Sorry, I'm not playing your game anymore.  I'm not interested in trying
to work with you anymore, because its totally impossible.  You're being
as obstructive as you have been from the very start, and as demonstrated
last night when you said "there is no mixer" in Liam's DPCM driver, you
don't know what you're talking about half the time.  Or, you're
intentionally making false statements.

There is no point persuing this any further; I'm not wasting any more
time on playing your stupid games.
