Deprecated function: Automatic conversion of false to array in uc_cart_block_view()

Problem/Motivation

There is a PHP 8 deprecation message in uc_cart_block_view():

Deprecated function: Automatic conversion of false to array is deprecated in uc_cart_block_view() (line 338 in  /sites/all/modules/ubercart/uc_cart/uc_cart.module).

The problematic code - see the $items variable:

      $items = FALSE;
      ...

      if ($product_count) {
        ...
        foreach (element_children($display_items['uc_cart_item']) as $key) {
          ...
          if (count(element_children($display_item))) {
            $items[] = array(
              'nid' => $display_item['nid']['#value'],
              'qty' => theme('uc_qty', array('qty' => $display_item['qty']['#default_value'])),
              'title' => $display_item['title']['#markup'],
              'price' => $display_item['#total'],
              'desc' => isset($display_item['description']['#markup']) ? $display_item['description']['#markup'] : FALSE,
            );
            ...
          }
        }
      }
