The nolintlint linter does not deny the use of `//nolint` Instead it allows us to enforce a common nolint style: - force that a linter name must be specified - do not add a space between `//` and `nolint` - make sure nolint is only used when there is actually a problem Signed-off-by: Paul Holzinger <pholzing@redhat.com>
