As well as its sibling of_device_get_match_data() has no such checks,
no need to do it in acpi_get_match_data().

First of all, we are not supposed to call fwnode API like this without
driver attached.

Second, if pure OF driver calls this function, it's weird to have ACPI
companion without ACPI ID in this case.

We talked about this during review.

of_match_device() does all the checking for the OF part. ACPI doesn't have
any checks.

Yeah, this patch is just plain incorrect AFAICS.
