Subject: net/mlx5: E-Switch, Fix an Oops in error handling code
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=388188fb58bef9e7f3ca4f8970f03d493b66909f;p=linux.git

net/mlx5: E-Switch, Fix an Oops in error handling code

[ Upstream commit 640fcdbcf27fc62de9223f958ceb4e897a00e791 ]

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")
