From 3bcfc7b90465efd337d39b91b43972162f0d1908 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Mon, 12 Jun 2023 21:25:33 +0300 Subject: [PATCH] drm/msm/dpu: do not enable color-management if DSPPs are not available We can not support color management without DSPP blocks being provided in the HW catalog. Do not enable color management for CRTCs if num_dspps is 0.
