Bug Description
[Impact]
Once screen is locked under gnome-shell, the screen never wakes up and
remains in blank forever.
[Fix]
"drm/i915: Create resized LUTs for ivb+ split gamma mode" makes gamma
LUT operations in atomic context, so userspace can no longer misuse libdrm.
"drm/i915: Rework legacy LUT handling" starts to use the reworked gamma
LUT.
Pull the whole series and series they depends upon to properly support
gamma LUT.
[Test]
The easier way to reproduce the issue is to
1) Login under Wayland
2) Logout and login under X
3) Go back to wayland
4) Super + L to screenlock
With the LUT reworked series applied, screen can always come back alive.
[Where problems could occur]
Regression can happen on refactoring patches with "no functional change
intended", let alone overhauls like this one.
So only OEM-6.1 and Unstable are targeted to contain the potential
regression.

Does it work with earlier kernels, meaning is this bug a regression in itself? Backporting 41 commits to an LTS kernel might cause issues in the future..
