Schema mismatch after version update

After last update, where one module produced an error, I have the following on admin/build/schema/compare :

simplenews_mail_spool

column error - difference on: size
declared: array('description' => t('TODO: please describe this field!'), 'type' => 'int', 'size' => 'tiny', 'not null' => TRUE, 'default' => 0)
actual: array('description' => t('TODO: please describe this field!'), 'type' => 'int', 'not null' => TRUE, 'default' => 0)
