Subject: [PATCH] drm/dp_mst: add missed nv50_outp_release in nv50_msto_disable
Date:   Fri,  6 Dec 2019 15:53:21 +0800
Message-Id: <20191206075321.18239-1-hslester96@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
To:     unlisted-recipients:; (no To-header on input)
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.
