This is not related to code move, is it? And if it is, it should be
described in the commit message.

And... this check broke display support at this point, didn't it? It's
never set, so none of the pipes are going to be checked.

Yeah, no pipe is checked. It passes real test without the check luckily.
Will move plane splitting patch before this check patch.
