How can I have Rows show posts from every category?

I'm guessing it has to do with changing these lines in content-rows.php

<?php
$cat_row = get_option('dev_buddydaily_featurecat_rows');
$cat_row_num = get_option('dev_buddydaily_featurecat_rows_num');
?>
<?php query_posts('category_name='. $cat_row . '&posts_per_page='. $cat_row_num . ''); ?>

I want every post to show, regardless of category.
