Respected maintainers, Looking at the code and the call trace reported by Syzbot, I understood that the issue lies in the drm_gem.c file in drm_gem_object_handle_put_unlocked(obj);. As per my understanding, I believe that a warning is given out when the DRM GEM object handle gets destroyed along with the function getting returned immediately. To take care of the warning only, I think that the WARN_ON can be removed with only the function getting returned when the object handle gets destroyed, without a warning. Or else, we can even have a message logging in the place of a direct warning which will give out the information that the object handle has been destroyed. I also think that the WARN_ON is given for debugging purposes and hence proposing a solution if the warning can be replaced with a simple message log. I am looking forward to getting help in this regard from the respected maintainers.
