At driver init no one can access modeset objects and we're
single-threaded. So locking is just cargo-culting here. Worse, with
the new ww mutexes and ww mutex slowpath debugging the mutex_lock
might actually fail, and we don't have the full-blown ww recovery
dance.
Which then leads to fireworks

single-threaded. So locking is just cargo-culting here. Worse, with
the new ww mutexes and ww mutex slowpath debugging the mutex_lock
might actually fail, and we don't have the full-blown ww recovery
