Subject: [PATCH v2] drm/nouveau/dispnv50: add missed nv50_outp_release in nv50_msto_disable
Date:   Thu, 12 Dec 2019 18:03:56 +0800

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

nv50_msto_disable() does not call nv50_outp_release() to match
nv50_outp_acquire() like other disable().
Add the missed call to fix it.
