There is an effort in progress to generate a QEMU Python package. As I'm not sure this old email is still valid, update it to not produce package with broken maintainer email. Patch created mechanically by running: $ sed -i 's,\(__email__ *= "\)stefanha@linux.vnet.ibm.com",\1stefanha@redhat.com",' \ $(git grep -l 'email.*stefanha@linux.vnet.ibm.com') Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: John Snow <jsnow@redhat.com> Message-id: 20200511082816.696-1-philmd@redhat.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
