Subject: [dpdk-dev] [PATCH 3/6] net/mlx5: fix unnecessary init in socket handle
Date: Wed, 27 May 2020 08:37:54 +0000	[thread overview]
Message-ID: <1590568677-11662-3-git-send-email-michaelba@mellanox.com> (raw)
In-Reply-To: <1590568677-11662-1-git-send-email-michaelba@mellanox.com>

In the mlx5_pmd_socket_handle function it calls the recvmsg function
which returns the number of bytes read. The function assigns this return
value into a ret variable defined at the beginning of the function.
Similarly in the mlx5_pmd_socket_init function the it calls the socket
function which returns a file descriptor for the new socket. The
function also assigns this return value into a ret variable defined at
the beginning of the function.

In both functions they initialize the variable when defining it,
however, in both cases they do not use any ret variable before assigning
the return value from the function, so the initialization is
unnecessary.

Clean the aforementioned unnecessary initializations.
