*Subject:* [PATCH v2] Revert "drm/amd/display: Enable Replay for static
screen use cases"
From: Ivan Lipski <ivlipski@xxxxxxx>
This reverts commit a92da5bc33ea99a861f6c422192af6072c145d2d.
V2: Reword commit message
[WHY]
This commit caused regression in which eDP's with PSR support,
but no Replay support (Sink support <= 0x03), failed enabling PSR
and all IGT amd_psr tests.
[HOW]
Reverted the patch.
Signed-off-by: Ivan Lipski <ivlipskI@xxxxxxx>
