There you go (and sorry for the late reply)

By the way, between the initial version of the GEM CMA PRIME patch and the
version that got merged in v3.10, commit
011c2282c74db120f01a8414edc66c3f217f5511 ("drm: prime: fix refcounting on the
dmabuf import error path") was introduced. The GEM CMA PRIME code in v3.10
thus has a refcounting bug :-(
Should this patch set go to -stable, or should we cook up a special fix ?
