Subject: [PATCH] drm/virtio: move drm_connector_update_edid_property() call
Date:   Fri,  5 Apr 2019 06:46:02 +0200
Message-Id: <20190405044602.2334-1-kraxel@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

drm_connector_update_edid_property can sleep, we must not
call it while holding a spinlock.  Move the callsize.
