Subject: drm/amd/display: Don't show stack trace for missing eDP
From: Mario Limonciello <mario.limonciello@xxxxxxx>
commit 7ad1dfc144cbf62702fd07838da8fd8a77921083 upstream.
Some systems are only connected by HDMI or DP, so warning related to
missing eDP is unnecessary. Downgrade to debug instead.
