Michel, Darrick,

Apparently you are using the therm_adt746x driver, so maybe you would
be interested in testing and carrying the following patch. I've sent it
to Colin Leroy, who is listed as the maintainer for this driver, 1.5
month ago, but did not hear back.

The ADT746x don't have any register at sub-address 0, so better use an
existing register for the initial test read.
