Use reusable value sets as allowed values for fields.

Code

function values_field_field_settings_form_validate(&$form, &$form_state) {

  // Grab the value of the values_field form element
  $values_field = $form_state['values']['field']['settings']['values_field'];
  if (!empty($values_field)) {

    // The "allowed_values_function" setting is built into the list module.
    // so all we need to do is supply our own custom function
    $form_state['values']['field']['settings']['allowed_values_function'] = 'values_field_content_allowed_values';
  }
  elseif ($form_state['values']['field']['settings']['allowed_values_function'] == 'values_field_content_allowed_values') {

    // If there's no value set chosen, but the allowed values function is still
    // set to values_field_content_allowed_values, we need to do a little
    // clean up and unset it so it doesn't run needlessly.
    $form_state['values']['field']['settings']['allowed_values_function'] = '';
  }
