there is no guarantee that i2c bus numbering will stay the same over
time (for example if hardware is added of removed, or simply due to
loading the drivers in a different order), passing the i2c bus by name
is more robust.
The i2c bus names are supposed to be unique. If you request a bus by
name and this name happens to not be unique, then the tools will play
it safe and quit. This is better than writing to the wrong device.
