In this case I am not seeing any particular issue, but with the introduction of devlink-sb for felix, a non-obvious decision had to be made as to where to put its cleanup method. When there's a convention in place, that decision becomes obvious. Signed-off-by: Vladimir Oltean Reviewed-by: Florian Fainelli --- Changes in v6: None. Changes in v5: None.
