[PATCH 1/2] drm: Allow mode object properties to be added after a device is registered

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When the colorspace property is registered on MST devices there is
no `obj_free_cb` callback for it in drm_mode_object_add().

Don't show a warning trace for __drm_mode_object_add() calls for
DRM_MODE_OBJECT_PROPERTY.
