From 21f75646a6c6bf29ba39d15f4c0c11d9d4243718 Mon Sep 17 00:00:00 2001
From: Nikola Cornij <nikola.cornij@amd.com>
Date: Thu, 25 Oct 2018 17:02:42 -0400
Subject: [PATCH 0802/2940] drm/amd/display: Consolidate
two-pixels-per-container check
[why]
The condition to check for two pixels per containter has become rather
long and is used in number of places.
[how]
Move the check to a helper function.
