From 6dbebf4da3616a14f43041b81a0881a7343ce5fc Mon Sep 17 00:00:00 2001 From: Joshua Aberback Date: Sun, 5 Apr 2020 16:41:11 -0400 Subject: drm/amd/display: Acknowledge wm_optimized_required [Why] If dc->clk_mgr->funcs->are_clock_states_equal is set, then wm_optimized_required is never checked. In that case, when going from a higher mode to a lower mode, wm_optimized_required remains true until the next mode change.
