Subject: [PATCH] RDMA/hns: return 0 rather than return a garbage status value
Date: Fri, 29 Sep 2017 21:13:08 +0100 [thread overview]
Message-ID: <20170929201308.4704-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
For the case where hr_qp->state == IB_QPS_RESET, an uninitialized
value in ret is being returned by function hns_roce_v2_query_qp.
Fix this by setting ret to 0 for this specific return condition.
Detected by CoverityScan, CID#1457203 ("Unitialized scalar variable")
