Unfortunately the patch doesn't keep my machine from crashing.

it seems that the problem now occurs in drm_atomic_get_connector_state.

(gdb) list *drm_atomic_get_connector_state+0x40
0xff0 is in drm_atomic_get_connector_state (drivers/gpu/drm/drm_atomic.c:652).
647              *
648              * Note that we only grab the indexes once we have the right lock to
649              * prevent hotplug/unplugging of connectors. So removal is no problem,
650              * at most the array is a bit too large.
651              */
652             if (index >= state->num_connector) {
653                     DRM_DEBUG_ATOMIC("Hot-added connector would overflow state array, restarting\n");
654                     return ERR_PTR(-EAGAIN);
