From 615d04017b2029292834f2cb9c97fe7857bef1be Mon Sep 17 00:00:00 2001

Subject: [PATCH 3335/4131] drm/amdgpu: drop compute ring timeout setting for
non-sriov only (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Sriov still wants these error messags on timeout. So, for sriov
use case, the timeout setting on compute rings is kept.
-v2: clean the code
