From 9e084a577869cd42ebc5a58c1ab258c89be87053 Mon Sep 17 00:00:00 2001 From: Peter Rosin Date: Thu, 13 Jul 2017 18:25:32 +0200 Subject: [PATCH] drm: gma500: remove dead code and pointless local lut storage The redundant fb helpers .gamma_set and .gamma_get are no longer used. Remove the dead code and hook up the crtc .gamma_set to use the crtc gamma_store directly instead of duplicating that info locally.
