From 650e723cecf2738dee828564396f3239829aba83 Mon Sep 17 00:00:00 2001 From: "Leo (Hanghong) Ma" Date: Fri, 8 May 2020 14:18:07 -0400 Subject: [PATCH] drm/amd/amdgpu: Update update_config() logic [Why] For MST case: when update_config is called to disable a stream, this clears the settings for all the streams on that link. We should only clear the settings for the stream that was disabled. [How] Clear the settings after the call to remove display is called.
