From 3f815fa943fb9e9d534de35dc743ff4318104b15 Mon Sep 17 00:00:00 2001
From: Harry Wentland <harry.wentland@amd.com>
Date: Tue, 6 Dec 2016 12:25:52 -0500
Subject: [PATCH 0051/4131] drm/amd/display: Fix warning. Set MAX_SURFACES to 3
Currently we never use more than 2 surfaces in all use cases.
This avoids pushing dc_commit_surfaces_to_target beyond a
stacksize of 1024.
