From 8c157e3b17b014c53856b9f949540a16eceb337c Mon Sep 17 00:00:00 2001
From: Leo Liu <leo.liu@amd.com>
Date: Fri, 25 May 2018 10:53:39 -0400
Subject: [PATCH 4564/5725] drm/amdgpu: remove unnecessary scheduler entity for
VCN
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It should be stateless, and no need for scheduler to take care specially.
