Do you even need to do anything at all? crc32c is provided by crc32c-intel at a higher priority already, so it should be used if it is available..

Unless the module is loaded the optimized algorithm will not be available for automatic use. Maybe your patch causes it to autoload because of the by-name reference? Identifying modules to load by CPUID will let userspace auto load the appropriate ones based on CPU...
