Unfortunately it looks like further vlv patches are still stalled due
to fried hw, and too many people are a bit annoyed about the unused
function warning.

So let's just rip it out, we can easily put it back in again.

It is my preference that you never merge code which you know will
produce a warning. I still stand by adding a __used for intermediate
patches.

Twasn't a shot at you... shot was fired at Daniel (although if you *did*
but in __used I wouldn't have had to shoot at Daniel).

Meh ok you can kill this function.  Vijay will be re-posting the code
that uses it (and adds it again) once he gets his hardware, unless I
beat him to it (still waiting on a new CPU).

I guess that counts as an ack ... patch merged for -next.
