I was a bit hesitant to do this change in the first place.
We can keep the current flow in the ams-delta to be on the safe side.
I'm going to send out another series for the omap platforms soon which will 
keep the error handling logic of ams-delta intact.

I don't think it worth the trouble to do this.
