[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.
