The array, returning an error from code sniffer

genima_log.module

/**
 * Implements hook_node_info().
 */
function genima_log_node_info() {
  // Returns an array defining a new node type.
  return array(
    'logged_item' => array(
      'name' => t('Logged Item'),
      'base' => 'genima_logged_item',
      'description' => t('A content type for logging items for use in Genima Log'),
      'help' => t('Add logged items, actions, notes, bugs and fixes here'),
      'has_title' => TRUE,
      'title_label' => t('Logged entry title'),
      'locked' = TRUE,
    ),
  );
}

Whats the cause / fix to this?

The code above follow this example:
https://api.drupal.org/api/drupal/modules%21node%21node.api.php/function/hook_node_info/7

Am trying to work out why code sniffer (with Drupal standards is getting upset) ?!

PHP_CodeSniffer found at least one issue. [error]
