How do you think of following code, Kalle?
/*
* If "dev->id" is negative we consider it as zero.
* The reason to do so is to avoid sysfs names that only make
* sense when there are multiple adapters.
*/
p_adap->nr = dev->id >= 0 ? dev->id : 0;
I found some i2c-gpio, i2c-ibm_iic.c and i2c-pxa.c using this code,
while others use your idea.

Thanks a lot
