Enabling Checks for this warning class are disabled by default. To enable them, add the following WARNING_FILTER rule to the project configuration file. 
WARNING_FILTER += allow class="Pointer Conversion to Same Size Integer"

Example 

/* Comments on this file reflect a platform where:
 * - int is the same width as pointer
 * - char is narrower than pointer
 * - long long int is wider than pointer
 *
 * If your platform has different type width relationships, you will see a different set of warnings.
