i2c: Warn on i2c client creation failure
i2c: Warn on i2c client creation failure
Warn when an i2c client creation fails. If we don't, the user will
never know something wrong happened, as i2c client creation is
typically called through an attach_adapter callback, those return value
we currently ignore for technical reasons.
