[Mesa-dev] [PATCH 3/4] ilo: unref old fence

[Rob Clark]

From: Rob Clark <robclark at freedesktop.org>

Some, but not all, state trackers will explicitly unref (and set to
NULL) the previous *fence before calling pipe->flush().  So driver
should use fence_ref() which will unref the old fence if not NULL.
