I remember patches fixing that. Since I usually don't take DTS patches,
I can't recall what happened to them. It might well be that those were
accepted and meanwhile new bad bindings got in.

I'd simply assume it was never tested. EEPROMs are often convenience
storage and not essential for a working board. Also, for historic
reasons, they are often used via the i2c-dev interface directly, so a
wrong binding with the kernel driver might simply go unnoticed.
