From 6dd201d2681dd336ff82afc7feaf94d0cfd08e65 Mon Sep 17 00:00:00 2001
From: Andrey Grodzovsky <Andrey.Grodzovsky@amd.com>
Date: Mon, 19 Jun 2017 11:38:15 -0400
Subject: [PATCH 0532/4131] drm/amd/display: MST atomic_get_property missing.
Missing function implementation was leading to EINVAL
in UMD thus not adding MST connector to X topology
and hence not getting set mode for it.
