Subject: drm/i915: Declare .(de)gamma_lut_tests for icl+
MIME-Version: 1.0

Git-commit: a37795cbdff243c198d9cf9615bd5d016bbfd546
Patch-mainline: v5.17-rc1

All interpolated gamma modes including the icl+ multi segment
mode require non-decreasing entries for the interpolation to
work correctly. For some reason we're forgetting to declare
that for icl+. Let us do so.
