Strict warning : Only variables should be passed by reference uc_termsofservice_general_form() line 131 uc_termsofservice.module

Hi,
The full message is :

Strict warning : Only variables should be passed by reference in uc_termsofservice_general_form() (line 131 in /home/mywebroot/www/drupalsubfolder/sites/all/modules/uc_termsofservice/uc_termsofservice.module).

I found a fix in uc_termsofservice_general_form() line 131 in uc_termsofservice/uc_termsofservice.module :
OLD CODE

  if ($node) {
    $form['tos_text'] = array(
      '#markup' => drupal_render(<strong>node_view($node, 'teaser')</strong>),
    );
    $form['tos_agree'] = array(

--->

NEW CODE

  if ($node) {
	$nodevw = node_view($node, 'teaser');
    $form['tos_text'] = array(
      '#markup' => drupal_render($nodevw),
    );
    $form['tos_agree'] = array(

I hope this helps.
