e.g. a quirk table has: {0x12, 0x9xxxxxxx}, {0x14, 0x9xxxxxxx}, {0x21, 0x02xxxxxx} while a machine only has {0x12, 0x9xxxxxxx}, {0x21, 0x02xxxxxx} and the NID 0x14 on the machine is a [Vendor Defined Widget] instead of a [pin complex]. In this situation, only the first loop can detect they are not matching.
