[PATCH 1/4] drm/atomic: Save flip flags in drm_plane_state
...he beginning is
if ((page_flip->flags & DRM_MODE_PAGE_FLIP_ASYNC) && !dev->mode_config.async_page_flip)
return -EINVAL;
We in DC explicitly set dev->mode_config.async_page_flip = true, any driver which is
Not supporting ASYNC flip will fail the IOCTL at this point.
Same in drm_mode_atomic_ioctl
