I just made a custom module that does the following in a .module file.

function entityreference_dragdrop_element_validate($element, &$form_state)
{
    // Whatever
}

The problem is the function entityreference_dragdrop_element_validate referenced in the form api #element_validate does not exist. (EntityReferenceDragDropWidget.php)
