This reverts commit f70f6baaa3bb0f8b280ac2eaea69bbffaf7de840.
---
This commit broke VAAPI surface export (found by bisection). I think the
observed behaviour with playback is consistent with surfaces not being updated
some of the time, so something to do with sharing? I tried setting
PIPE_BIND_SHARED on the surfaces explicitly, but that didn't help so I'm
somewhat unclear what's going on exactly.
I've included this patch in the series as a revert because it makes it testable
for other people, but it would be better if someone who understands how these
interact could have a look and decide how to fix it properly.
Thanks,
- Mark
