Subject: [PATCH 2/2] drm/nouveau: Fix runtime PM leak in nv50_disp_atomic_commit()
Date:   Tue,  3 Jul 2018 18:06:00 -0400
Message-Id: <20180703220602.16664-3-lyude@redhat.com>
In-Reply-To: <20180703220602.16664-1-lyude@redhat.com>
References: <20180703220602.16664-1-lyude@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A CRTC being enabled doesn't mean it's on! It doesn't even necessarily
mean it's being used. This fixes runtime PM leaks on the P50 I've got
next to me.
