Note that I'm not too happy with this change. I understand the need for
unique I2C bus names, however changing names for legacy devices which
have a single bus is bad. The name can be used in sensors.conf or in
scripts to uniquely reference a specific I2C bus, and changing it will
break that.
So I'd rather only change the names for the mux'd SB800 ports where
this is needed, and leave the rest untouched.
Also I don't much like "SDA0"... in bus names. SDA0 standard for
"serial data 0" is the name of one of the pins for SMBus channel 0. The
other one is SCL0 ("serial clock 0".) There's no reason to include a
pin name in the I2C adapter name string, just the channel number
matters.
I'll submit a patch later today that implements things the way I would
like, and you can comment on it.
