+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.
