+From d528f8e70759802d5d89cd3f4de1684dee74ca4f Mon Sep 17 00:00:00 2001

+Subject: [PATCH 2620/4131] drm/amd/display: Fix no display on Fiji
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Allocate memory for the second pipe allocate_mem_input() needs to
+be done prior to program pipe front end. It shows sensitive to
+Fiji. Failure to do so will cause error in allocate memory 
+allocate_mem_input() on the second connected display.
