Hi Guenter,

Again, sorry for the late review.

A device ID of 0, unfortunately, is very fragile and thus certainly
doesn't deserve a confidence value of 8. 6, tops. It would also make
sense to check the unused bits in register 0xbf (Alert Mode / $conf2)
for this device, to make the detection somewhat more reliable, as we do
for many other LM90-compatible chips.

You mean SA.
