Duplicate feed links created when a rss feed is executed more then once on a page.

Without getting into the why I am executing a view twice. I noticed that it caused duplicate RSS feed links to be added to a page's header.

The problem is that the views_plugin_style_rss() plugin is calling drupal_add_link() instead of drupal_add_feed(). Using drupal_add_feed() prevents duplicate link from being created and drupal_add_link() does not.

Below is the current code in views/plugins/views_plugin_style_rss.inc - LINE 34 for views-6.x.2.x

$this->view->feed_icon .= theme('feed_icon', $url, $title);
drupal_add_link(array(
  'rel' => 'alternate',
  'type' => 'application/rss+xml',  
  'title' => $title,
  'href' => $url
 ));

The change would simply be

$this->view->feed_icon .= theme('feed_icon', $url, $title);
drupal_add_feed($url, $title);

This change could also be applied to views-6.x.3.x and views-7.x-3x.

Hope this make sense. Anyway it is nice to post a suggestion that simplifies code (vs creating more).

Thanks,
