Yes you are right! In my previous review, I mixed up
of_i2c_register_devices (with plural 's') with of_i2c_register_device
(without plural 's'). I could now verify your findings by rebinding an
adapter which had DT bindings for clients attached. With every rebind
cycle, the refcount for the client increased.

I did some rebasing, because your patch didn't apply to a v4.15
codebase. Now, applied to for-current, thanks!
