Can this patch be applied to display more than 10 entity references in a dropdown menu?

I have a content type where affiliations (entity references) can be selected when entering conference participants, but only 10 affiliations show at any given time in the dropdown list. This is a problem when there are more than 10 affiliation that have the same values, e.g., “Pennsylvania.” A patch has recently been released (5/22/17) to allow the number of hits in the dropdown to be configurable. Can this patch please be applied: https://www.drupal.org/node/2185019

Note: A clear cache needs to be manually applied to prevent error from displaying

Thanks,
