Subject: [PATCH 1/2] Input: atkbd - make dmi callback functions return 1

We only care about if there is a 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.
