Subject: [net-next 03/15] net/mlx5: Bridge, fix uninitialized variable usage
Date: Thu, 2 Sep 2021 12:05:42 -0700 [thread overview]
Message-ID: <20210902190554.211497-4-saeed@kernel.org> (raw)
In-Reply-To: <20210902190554.211497-1-saeed@kernel.org>
From: Vlad Buslov <vladbu@nvidia.com>
In some conditions variable 'err' is not assigned with value in
mlx5_esw_bridge_port_obj_attr_set() and mlx5_esw_bridge_port_changeupper()
functions after recent changes to support LAG. Initialize the variable with
zero value in both cases.
Reported-by: Colin King <colin.king@canonical.com>
Reported-by: Tim Gardner <tim.gardner@canonical.com>
Fixes: ff9b7521468b ("net/mlx5: Bridge, support LAG")
