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.
