drm: fix fb-helper vs MST dangling connector ptrs (v2)
VT switch back/forth from console to xserver (for example) has potential to go horribly wrong if a dynamic DP MST connector ends up in the saved modeset that is restored when switching back to fbcon. When removing a dynamic connector, don't forget to clean up the saved state. v1: original v2: null out set->fb if no more connectors to avoid making i915 cranky Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1184968 Cc: stable@vger.kernel.org #v3.17+ Signed-off-by:Rob Clark <robdclark@gmail.com> Signed-off-by:
