Subject: [PATCH][V2] IB/hns: fix memory leak on ah on error return path
Date: Tue, 8 Aug 2017 18:41:02 +0100 [thread overview]
Message-ID: <20170808174102.28568-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
When dmac is NULL, ah is not being freed on the error return path. Fix
this by kfree'ing it.
Detected by CoverityScan, CID#1452636 ("Resource Leak")
Fixes: d8966fcd4c25 ("IB/core: Use rdma_ah_attr accessor functions")
