3.16.37-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dotan Barak <dot...@dev.mellanox.co.il>
commit 5b420d9cf7382c6e1512e96e02d18842d272049c upstream.
When RC, UC, or RAW QPs are created, a qp object is allocated (kzalloc).
If at a later point (in procedure create_qp_common) the qp creation fails,
this qp object must be freed.
Fixes: 1ffeb2eb8be99 ("IB/mlx4: SR-IOV IB context objects and proxy/tunnel SQP
support")
