Even if R-Car I2C received NACK, after that it might receive ACK
by HW auto restart. In case of that, driver would continue process.
If R-Car I2C didn't receive ACK, the driver would detect timeout
and would report NACK as -ENXIO.

Excuse me, but what exactly is HW auto restart in this case? Is it a
feature of the I2C slave?
Thanks,
