I2C drivers were required to have an I2C device ID table even if were for devices that would only be registered using a specific firmware interface (e.g: OF or ACPI). But commit da10c06a044b ("i2c: Make I2C ID tables non-mandatory for DT'ed devices") changed the I2C core to relax the requirement and allow drivers to avoid defining this table. Unfortunately it only took into account drivers for OF-only devices and forgot about ACPI-only ones, and this was fixed by commit c64ffff7a9d1 ("i2c: core: Allow empty id_table in ACPI case as well"). But the latter didn't update the original comment, so it doesn't reflect what the code does now.
