Subject: [PATCH] net/mlx5: potential error pointer dereference in error handling
Date: Fri, 03 May 2019 12:28:39 +0000	[thread overview]
Message-ID: <20190503122839.GB29695@mwanda> (raw)

The error handling was a bit flipped around.  If the mlx5_create_flow_group()
function failed then it would have resulted in dereferencing "fg" when
it was an error pointer.

Fixes: 80f09dfc237f ("net/mlx5: Eswitch, enable RoCE loopback traffic")
