Subject: [net 7/7] net/mlx5: E-Switch, Fix an Oops in error handling code
Date: Tue, 21 Mar 2023 14:11:35 -0700	[thread overview]
Message-ID: <20230321211135.47711-8-saeed@kernel.org> (raw)
In-Reply-To: <20230321211135.47711-1-saeed@kernel.org>

From: Dan Carpenter <error27@gmail.com>

The error handling dereferences "vport".  There is nothing we can do if
it is an error pointer except returning the error code.

Fixes: 133dcfc577ea ("net/mlx5: E-Switch, Alloc and free unique metadata for match")
