Of course, I just had to say that for someone to come to me with a
real-world example of I2C device with 10-bit address that we want to
support in Linux. So this patch is delayed for now until this driver is
submitted, and will be discarded if this happens. Instead we'll have to
fix the 10-bit address support.
