Subject: [PATCH] iw_cxgb4: fix over-dereference when terminating
Date: Wed, 02 Apr 2014 16:18:52 -0500 [thread overview]
Message-ID: <20140402211851.11219.28678.stgit@build.ogc.int> (raw)
Need to get the endpoint reference before calling
rdma_fini(), which might fail causing us to not
get the reference.
