Right. So probe_new() in i2c no longer has the id parameter and the
users are supposed to call i2c_match_id() themselves but
i2c_device_match() still expects the id_table to be present in struct
i2c_driver. I should have tested it with some board that uses platform
data.

Consider this patch dropped.

Thanks for spotting that,
