Comment # 2 on bug 1169316 from Jean Delvare

Sorry, missed that one.

Historically, support for the Nuvoton W83677HG-I and derivative was first added
to the w83627ehf driver, so that's the driver recommended by sensors-detect.
Later, support for the same device was also added to the nct6775 driver. In
kernel v5.6, support was removed from the w83627ehf driver to avoid maintaining
duplicate code, however sensors-detect was not updated accordingly, so it is
now pointing to the wrong driver.

I guess your problem appeared when you updated to kernel v5.6.

I will submit a fix upstream, and will also patch our sensors package. Thanks
for the reporting the problem.
