Subject: [PATCH net] net/mlx5: E-Switch, Fix an Oops in error handling code
Date: Mon, 27 Feb 2023 14:16:10 +0300 [thread overview]
Message-ID: <Y/yQ+kk/cQdXKBLw@kili> (raw)
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")
Signed-off-by: Dan Carpenter <error27@gmail.com>
