Why does drm/msm, a driver not using ttm at all, block ttm refactorings?
We can just check whether the TTM using driver is potentially using locked
final unref and have a special version of
drm_gem_object_put_guaranteed_unlocked or whatever the bikeshed will look
like, which doesn't have the migth_lock.

Anyway, deed is done now :-)
