Why would you alter the semantics of of_i2c_register_devices()? Besides, this function doesn't have a return value.

In general, tangbin has a point, the error reporting is doubled. Lower layers already report, so both(!) callers of of_i2c_register_device do not need to. Since I am refactoring all this anyhow in "[RFC PATCH 5/7] i2c: of: error message unification", I think I will just drop error reporting in the callers there when resending the series (giving tanbin credits for the removal). Is this okay with everyone?
