From c25abff511ad058e473c663286463a41bfc968f5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 27 Mar 2019 17:50:44 +0200 Subject: [PATCH] drm/i915: Drop the pointless linear legacy LUT load on CHV MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We now bypass the legacy LUT when it's not needed, so no point in filling it up with a linear LUT.
