Subject: [PATCH 4/7] sna: Dump fences also on -ENOBUFS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since kernel commit 78d2ad7eb4e1 ("drm/i915/gt: Fix
-EDEADLK handling regression") running out of fences
will result in -ENOBUFS instead of -EDEADLK (the latter
having been stolen by ww mutextes for their internal use).
Adjust the fence dumping to expect either errno value.
