From 95d939bb97ff9be101ae4ceeb322535589da2190 Mon Sep 17 00:00:00 2001 From: Stanislav Lisovskiy Date: Mon, 27 Mar 2023 09:42:17 +0300 Subject: [PATCH] drm/i915: Use compressed bpp when calculating m/n value for DP MST DSC For obvious reasons, we use compressed bpp instead of pipe bpp for DSC DP SST case. Lets be consistent and use compressed bpp instead of pipe bpp, also in DP MST DSC case.
