[PATCH 4.19 180/205] drm/etnaviv: fix bogus fence complete check in timeout handler

From: Greg Kroah-Hartman
Date: Mon Nov 19 2018 - 11:38:11 EST


4.19-stable review patch. If anyone has any objections, please let me know.

------------------

From: Lucas Stach <l.stach@xxxxxxxxxxxxxx>

commit 6fce3a406108ee6c8a61e2a33e52e9198a626ea0 upstream.

The GPU hardware fences and the job out-fences are on different timelines
so it's wrong to compare them. Fix this by only looking at the out-fence.

timeout handler)
