From 0e8b18200cfac4a40f7e7636fb1a5892f7d04667 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4080/4256] drm/amd/display: Skip DIG Check if Link is Virtual
for Display Count
[WHY]
Without a check for virtual links, every link's DIG was getting
checked for enabled or disabled. If link was virtual, since it
did not have a DIG, this would cause issues.
[HOW]
Skip DIG Enable check if link is virtual and add virtual link to
to display count.
