Use drm_universal_plane_init to create the planes, create the primary plane first and use drm_crtc_init_with_planes to associate it with the crtc. This gets rid of the unused fallback primary plane previously created by drm_crtc_init and fixes a NULL pointer dereference issue that can be triggered by a modeset from userspace when fbdev helpers are enabled [1].
