Most other I2C/SMBus hardware monitoring drivers indeed do not check
the status on I2C transactions and assume they were successful. This is
bad, but OTOH in a vast majority of cases it doesn't cause problem.
SMBus appears to be very reliable in practice.

Not to say that I do not encourage driver authors to check the status
of I2C transactions, but this is definitely not mandatory to get your
driver accepted in mainline.
