amdgpu dropping load callback triggers WARN_ON in __drm_mode_object_add

Michel Dänzer michel at daenzer.net
Fri Apr 3 16:30:09 UTC 2020


I'm getting the attached WARNING splats since amdgpu dropped its load
callback. They're from

	WARN_ON(!dev->driver->load && dev->registered && !obj_free_cb);

in __drm_mode_object_add.

I'm not sure how to address this, since obj_free_cb is always NULL here,
and I don't think MST connectors getting added after dev->registered is
set can be avoided?
