We only care about if there is any successful match from the table (or no match at all), we can make dmi_check_system return immediately if we have a successful match instead of iterate thorough the whole table. Make the dmi callback function return 1 then dmi_check_system will return immediately if we have a successful match. I think current implementation already assumes there is exactly one match or no match at all. If there are multiple successful matches then it is a bug, because new matches will override some variables such as lifebook_use_6byte_proto and desired_serio_phys.
