Subject: [dpdk-stable] [PATCH v2 2/4] net/mlx5: fix missing validation of null pointer
Date: Thu, 2 May 2019 18:01:55 +0300 [thread overview]
Message-ID: <c85536ec3c5ab40ef85f11ca0d175d15277f2a83.1556809050.git.dekelp@mellanox.com> (raw)
In-Reply-To: <cover.1556809050.git.dekelp@mellanox.com>
Function mlx5_rxq_ibv_release() is called in several places.
Before each call except one, the input parameter is validated to make
sure it is not null.
This patch adds the missing validation where it is missing.
Fixes: af4f09f28294 ("net/mlx5: prefix all functions with mlx5")
Cc: stable@dpdk.org
