Bug Description
[Impact]
OEM-6.1 1018 picks up this patch which was accidentally introduced even though reverted upstream.
- drm/amd/display: edp do not add non-edid timings
It's already reverted in 6.5 and being reverted in 6.1.42, can you please revert in advance in Ubuntu's kernel so we don't have the regression for a whole Canonical kernel cycle?
It will break mirror mode for all external monitors.
Here is the discussion on the revert.

[Test case]
Check mirror mode with the commit reverted.
[Where things could go wrong]
This is an upstream revert removing a broken commit, so it should not cause unrelated issues.
