Otherwise we'd still end up w/ the plane attached to the CRTC, and seemingly active, but without an FB. Which ends up going *boom* in the drivers. Slightly modified version of Daniel's irc suggestion. Note that the big problem isn't drivers going *boom* here (since we already have the situation of planes being left enabled when the crtc goes down). The real issue is that the core assumes the primary plane always goes down when calling ->set_config with a NULL mode. Ignoring that assumption leads to the legacy state pointers plane->fb/crtc getting out of sync with atomic, and that then leads to the subsequent *boom* all over the place.
