From 186a555a1e2bfbd94d24d59ef7b42731d0e7fa70 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4357/5725] drm/amd/display: Check dc_sink every time in MST
hotplug
Extended fix to: "Don't read EDID in atomic_check"
Fix issue of missing dc_sink in .mode_valid in hot plug routine.
Need to check dc_sink everytime in .get_modes hook after checking
edid, since edid is not getting removed in hot unplug but dc_sink
doesn't.
