From efc8278eecfd5e6fa36c5d41e71d038f534fe107 Mon Sep 17 00:00:00 2001
From: Anson Jacob <Anson.Jacob@amd.com>
Date: Thu, 18 Feb 2021 19:42:57 -0500
Subject: Revert "drm/amd/display: reuse current context instead of recreating
one"
This reverts commit 8866a67ab86cc0812e65c04f1ef02bcc41e24d68.
Reason for revert: This breaks hotplug of HDMI on some systems,
resulting in a blank screen. Caused general hangs on boot/hotplugs.
