From a37795cbdff243c198d9cf9615bd5d016bbfd546 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 14 Oct 2021 21:18:55 +0300 Subject: [PATCH] drm/i915: Declare .(de)gamma_lut_tests for icl+ MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
