From: Parav Pandit parav@mellanox.com Date: Thu, 2 Nov 2017 15:22:27 +0200 Subject: IB/core: Avoid unnecessary return value check
From: Parav Pandit parav@mellanox.com
commit 2e4c85c6edc80fa532b2c7e1eb3597ef4d4bbb8f upstream.
Since there is nothing done with non zero return value, such check is avoided.
