Syntax error in code with 1.11.1 update, worked with 1.10.2

Syntax error in code with 1.11.1 update, worked with 1.10.2

So as of version1.11.1 this string of code no longer works and throws an error.  This is the error - Error: Syntax error, unrecognized expression: #rsmn_vehicle_make option[value=].  How could I change this to work with the latest version?
  1. $("#rsmn_vehicle_model option[value='<?php if(isset($qinfo['model'])){echo stripslashes($qinfo['model']);} ?>']").attr('selected','selected');
