From 823057fc0a2c088bcbecfaac933a131e93385b75 Mon Sep 17 00:00:00 2001 From: "Leo (Sunpeng) Li" Date: Thu, 19 Jul 2018 08:22:16 -0400 Subject: [PATCH] drm/amd/display: Use requested HDMI aspect ratio commit e11d41472a50742c16d53c968e143fb498fa482f upstream. [Why] The DRM mode's HDMI picture aspect ratio field was never saved in dc_stream's timing struct. This causes us to mistake a new stream to have the same timings as the old, even though the user has requested a different aspect ratio. [How] Save DRM's aspect ratio field within dc_stream's timing struct.
