temperature input value of feature 'temp2' of chip 'thinkpad-isa-0000' is unavailable

Hi,
small issue I think, but it's a confusing one. Using latest code in the repo.

(relevant) sensors:

thinkpad-isa-0000
Adapter: ISA adapter
fan1:           0 RPM
CPU:          +40.0°C  
GPU:              N/A  
temp3:        +40.0°C  
temp4:         +0.0°C  
temp5:        +40.0°C  
temp6:        +40.0°C  
temp7:        +40.0°C  
temp8:            N/A 

(relevant) config:

sensors:
  - chip: thinkpad-isa-0000
    ids: [ CPU, GPU, temp3, temp4, temp5, temp6, temp7, temp8 ]

output:

sudo thinkfan -nv
ERROR: temperature input value of feature 'temp2' of chip 'thinkpad-isa-0000' is unavailable: Can't read

expected output: ERROR: temperature input value of feature 'GPU' (GPU instead of temp2)

(if I would put GPU at the end of the ids array it would also say 'temp2')
(removing GPU and temp8 from my config fixed the issue for me)

That sounds very weird. From a code review (currently have no hardware available to reproduce this) I'd say this must be a libsensors bug, because we first lookup the feature by name (i.e. GPU in this case), but then continue on with the libsensors representation of the feature. In the error message, we then use whatever libsensors says the offending feature's name is. So it looks to me like libsensors just has the wrong feature name in its internal data structure.
