The MODULE_DEVICE_TABLE() macro already checks for MODULE defined,
so the extra check here is not necessary.

I'd rather know what this table is used for in the first place.

Seems it's really just used for the module loader, while actual probing
is using a different table. IMHO, the worst thing my patch could do is
introducing a warning on unused variable (IMHO shouldn't happen when
it's static const).

I've just rewritten it to move everything into i5k_amb_ids ... just need
to run build tests on it (unfortunately can't run-test, as I don't have
that device).

You are wrong. You'll need __maybe_unused qualifiers for those variables
to avoid the warning.
