From 78109d230b797077d58600694ca427b9830eb600 Mon Sep 17 00:00:00 2001 From: Harry Wentland Date: Mon, 16 Oct 2017 22:10:31 -0400 Subject: [PATCH] Revert "amdgpu/dc: drop dml display_mode_support.c (v2)" This reverts commit 5e0adbff084f33202db36be798c583a115990392. Unfortunately these clash with our DML update from the HW guys. Will attempt to reroll them after.
