Subject: [dpdk-dev] [PATCH] ethdev: remove useless pointer initialization
Date: Tue, 24 Jan 2017 21:28:35 +0100	[thread overview]
Message-ID: <20170124202835.1271-1-emmanuel.roullit@gmail.com> (raw)

Found with clang static analysis:
lib/librte_ether/rte_ethdev.c:2467:22:
warning: Value stored to 'dev' during its initialization is never read
struct rte_eth_dev *dev = &rte_eth_devices[port_id];
                    ^~~   ~~~~~~~~~~~~~~~~~~~~~~~~~

Fixes: 61207d014fc9 ("ethdev: fix data reset when allocating port")
