The fact that there are _build_ _errors_ indicate that a patch which
introduced this crap _was_ _broken_. The fact that it was _reported_
as broken well before the merge window and still went in during the
merge window indicates that the OMAP workflow with regard to patches
is simply BROKEN.

And the fact that you can't recognise that makes _you_ part of the
problem.

There are no excuses for this.

And more - wtf those commit IDs you mention have to do with my build
error with twl-common.c I've no idea. The breakage was not introduced
by either of the commits you mention, but b22f954 (OMAP4: Move common
twl6030 configuration to twl-common).

So please, stop this disinformation right now and get more of a clue.

Thanks.
