Remove entry meta for post types

functions.php

<?php
add_action( 'init', 'sample_remove_entry_meta', 11 );
/**

 */
function sample_remove_entry_meta() {

	remove_post_type_support( 'post-type', 'genesis-entry-meta-before-content' );
	remove_post_type_support( 'post-type', 'genesis-entry-meta-after-content' );

}

Is there a reason you have the action at priority 11? Genesis sets this up at priority 11, so setting to priority 12 or more ensures this will run after Genesis has done its initial setup of meta support for post types.
