From: Leon Romanovsky <leonro@nvidia.com> Move devlink_register() to be last command in devlink configuration sequence, so no user space access will be possible till devlink instance is fully operable. As part of this change, the devlink_params_publish call is removed as not needed. This change fixes forgotten devlink_params_unpublish() too.
