@return missing in doc comment of get_admin_page_parent function

@return is missing in the Doc comment of get_admin_page_parent function.

Also I have a question. At the end of the function body we are returning hard coded empty string i.e. return '';

Why don't we return the $parent_file instead? Since we are already returning the value from rest of the if-else blocks and foreach loop the last final statement either will return an empty string or a value assigned to $parent_file variable.

if( empty( $parent_file ) ) {
   $parent_file = '';

return $parent_file;

Since get_admin_page_title function is also missing the @return in Doc comment I am uploading a revised patch which combines both the functions.

Given PHPs type coercion, this really could just return $parent_file; without any check for empty, the caller should be responsible for checking for empty().

Returning $parent_file could have unintended side-effects. The check for empty on $parent_file effects a global variable and does not necessarily have any correlation to the return statement.
