Description

The thermal sensors on my Thinkpad are no longer working with the latest version of coreboot. Normally, the values should look like this:

# cat /proc/acpi/ibm/thermal 
temperatures:   68 0 0 0 0 0 0 0

# sensors thinkpad-isa-0000
thinkpad-isa-0000
Adapter: ISA adapter
fan1:        3440 RPM
temp1:        +68.0°C

Now they look like this instead:

# cat /proc/acpi/ibm/thermal                                             
temperatures:   -128 0 0 0 0 0 0 0

# sensors thinkpad-isa-0000
thinkpad-isa-0000                                                                
Adapter: ISA adapter                                                             
fan1:           0 RPM                                                            
temp1:            N/A

It seems that this patch broke things: https://review.coreboot.org/c/coreboot/+/51072
