lintian. how to shut it up?

[Hleb Valoshka <375gnu@gmail.com>]

Hi team.

I'm using Lintian v2.5.35~bpo8+1, ruby-locales contains 2 gzipped
files. As these files came from upstream I want make lintian to shut
up.

I put file debian/lintian-overrides with content:
ruby-locale: package-contains-timestamped-gzip
usr/share/ruby-locale/data/languages.tab.gz
usr/share/ruby-locale/data/regions.tab.gz

But it still reports

W: ruby-locale: package-contains-timestamped-gzip
usr/share/ruby-locale/data/languages.tab.gz
W: ruby-locale: package-contains-timestamped-gzip
usr/share/ruby-locale/data/regions.tab.gz

How to silence it?
