Subject: [net 1/7] net/mlx5: Bridge, fix uninitialized variable usage
Date: Tue,  7 Sep 2021 14:24:14 -0700	[thread overview]
Message-ID: <20210907212420.28529-2-saeed@kernel.org> (raw)
In-Reply-To: <20210907212420.28529-1-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.
