Subject: drm/i915: Enable pipe gamma for the overlay
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 7cd0f22019feef75197d4b9c4d8eea1914bc0d13
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
We pass the plane data through the pipe gamma for all the other
planes. Can't see why we should treat the overlay differently,
so let's enable pipe gamma for it as well.
