Subject[PATCH 4.14 095/164] IB/core: Avoid unnecessary return value check
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Parav Pandit <parav@mellanox.com>

commit 2e4c85c6edc80fa532b2c7e1eb3597ef4d4bbb8f upstream.

Since there is nothing done with non zero return value, such check is
avoided.
