The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
Fixes: af503716ac14 ("i2c: core: report OF style module alias for
devices registered via OF")

Sorry for the spam, but after rethinking, I think some description in
commit message is improper. Hence I updated it in v4. Please review that
one instead.
