Subject: ilo: unref old fence
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=749dced4b363963b2230a18b0776fa92653116b8;p=mesa.git

ilo: unref old fence

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.
