Subject: [WIP PATCH 04/15] drm/dp_mst: Stop releasing VCPI when removing ports from topology
Date:   Thu, 13 Dec 2018 20:25:33 -0500
Message-Id: <20181214012604.13746-5-lyude@redhat.com>
In-Reply-To: <20181214012604.13746-1-lyude@redhat.com>

Precedence: bulk

This has never actually worked, and isn't needed anyway: the driver's
always going to try to deallocate VCPI when it tears down the display
that the VCPI belongs to.
