Subject: [dpdk-dev] [PATCH v2] net/softnic: fix resource leak for pipeline
Date: Mon, 27 Apr 2020 18:15:51 +0100	[thread overview]
Message-ID: <20200427171551.82235-1-jasvinder.singh@intel.com> (raw)
In-Reply-To: <20200427140325.83191-1-jasvinder.singh@intel.com>

For sending request messages to data plane threads, the
caller invokes pipeline_msg_send_recv() function which never
returns null response. Thus, removed redundant check on
the returned response.

Coverity Issues: 357676, 357680, 357681, 357682, 357690, 357693, 357711,
357722, 357725, 357734, 357739, 357743, 357747,357762, 357766, 357787

Fixes: 6d4d05402501 ("net/softnic: add command to read stats")
Fixes: 202905f3ee4d ("net/softnic: add command to create objects")
Fixes: ee19326a4b1e ("net/softnic: add command for pipeline table entries")
Fixes: 9bc0ce0ad17c ("net/softnic: add command for meter action")
Fixes: 2505030a8383 ("net/softnic: add command for TTL action")
