From 4fbb3ae219d2da0e21352c4eb1af6269b832ac10 Mon Sep 17 00:00:00 2001 From: Bernard Zhao Date: Mon, 12 Oct 2020 04:46:16 -0700 Subject: [PATCH] drm/amd/display: remove no need return value Functions (disable_all_writeback_pipes_for_stream & dc_enable_stereo & dc_post_update_surfaces_to_stream) always return true, there is no need to keep the return value. This change is to make the code a bit more readable.
