Comment # 20 on bug 1231312 from Jean Delvare

Thanks. So the issue is that commit b3e992f69c23 ("hwmon: (jc42)  Strengthen
detect function") requires that the capability register value has certain bits
sets for TSE2004-compliant devices (which is what you have). The new test
mandates that bits 0, 1, 2, 5, 6 and 7 of this register are set. Your register
value is 007f, which means that bits 0, 1, 2, 5 and 6 are indeed set but bit 7
is not.

I just reported the issue upstream, we'll see what they decide. For the time
being, I can write a candidate fix which relaxes the test a bit, and then we
can build a test kernel for you.
