As mentioned before, historically i2c devices would instantiate based
on the i2c match table. You are claiming that this is no longer the case.
The above is no evidence; that would require a log output on an affected
system showing that the sensors are not or no longer longer instantiated.

I am not absolutely opposed to adding the nodes, but the explanation
needs to match reality. If you can not provide evidence from an actual
boot log, I'll have to implement a tmp401 device model in qemu and test
myself. That will take a while.
