Obviously, I don't know much about the specs and their wording. Still I wonder if we can't call it a zero length transfer? This is allowed by the I2C standard and SMBus has even a proper name for it (SMBUS_QUICK). From my point of view, I would not say it is device specific because devices are expected to ACK such a message.
