drm_mode_page_flip_ioctl() cannot deal with the in between phase of the transitioning to atomic modeset support. Once we start using drm_helper_crtc_mode_set(), we start setting plane->state on the primary plane. But we are not fully atomic yet so then set both plane-state->fb and plane->fb. If both plane-state->fb and plane->fb are set drm_mode_page_flip_ioctl() gets confused and stops calling drm_framebuffer_get() on the new fb while still calling drm_framebuffer_put() on the old fb. The current page_flip implementation expects drm_mode_page_flip_ioctl() to take care of both and once we switch to drm_atomic_helper_page_flip() that will expect neither to be done, taking care of both itself. So for the transition we need to remove page_flip support and then after the transition is complete and we set DRIVER_ATOMIC in our driver_features, we can start using drm_atomic_helper_page_flip().
