While at it, see if you want to rename this variable as well to something
smaller, like "failed". I didn't touch it as it is a matter of personal choice,
so leaving it to you..

Add an I2C bus driver for virtio para-virtualization.
The controller can be emulated by the backend driver in
any device model software by following the virtio protocol.
The device specification can be found on
