In this case,\namdgpu_ib_free(ring->adev, ...) will be called, which would crash the\nmachine because the ring value is bogus.\n\nTo fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this\nbecause the device is actually not used in this function.\n\nThe next commit will remove the ring argument completely.\n\n(cherry picked from commit 2ae520cb12831d264ceb97c61f72c59d33c0dbd7)"
