Subject: Revert bad backport of "drm/radeon: hold reference to fences in radeon_sa_bo_new"
From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
This reverts commit 50353e6f86eb2ac46ffe3cc0b9f9a11ddc8a9410, which is
commit f6ff4f67cdf8455d0a4226eeeaf5af17c37d05eb upstream, as it was
backported to the 3.14-stable tree incorrectly. A correct fix will
happen next.
