From 28adce9f6ed1135f7eca199ff9ed4557de48bd93 Mon Sep 17 00:00:00 2001 From: Yongqiang Sun Date: Fri, 8 Jun 2018 13:07:53 -0500 Subject: [PATCH 4796/5725] drm/amd/display: Check scaling ration not viewports params. In case of roation, width and height in viewport is difference between viewport and h_active and v_active, while this is not scaling. The right way is check ratios in scaling data, to determine it is a scaling case or not.
