From 450d96615a8b39f767d26e261976925899e05ae5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1077/4131] drm/amd/display: Don't report fake sink as
connected
This was missed in the previous fake sink change. The fake sink
allows us to enable a pipe with a disconnected display. We
shouldn't report it as connected.
