From 8b18b785ebe9262162422930f9ddea9b5dd9d4b3 Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Wed, 3 Dec 2014 17:07:22 +1000
Subject: subdev: always upcast through nouveau_subdev()/nouveau_engine()

Has additional safeties for one.  For two, needed for an upcoming
commit that removes abuse of nouveau_object.engine.
