rpmlint show error then in source code present incorrect FSF address and we have recomendation to correct it https://fedoraproject.org/wiki/Common_Rpmlint_issues#incorrect-fsf-address
According this recomendation correct address can be taken from http://www.gnu.org/licenses/old-licenses/gpl-2.0.txt
... Boston, MA 02110-1301 USA

But it has different ZIP-code from address present on this page https://www.fsf.org/about/contact/
