Subject: Dell Latitude E6440 & i8k

Hello,

on Dell Latitude E6440 driver i8k reporting total nonsense values

$ sensors
i8k-virtual-0
Adapter: Virtual device
Right Fan:   93450 RPM
CPU:          +57.0°C  
temp2:        +57.0°C  
temp3:        +40.0°C  
temp4:       +127.0°C

Right Fan and temp4 are for sure incorrect.

Value temp4 is always 127 and is never changing, but value for 
Right Fan is increasing when fan is more noisy. So it looks like 
value for Right Fan is not correctly normalized or multiplier is 
incorrect.

And name "Right" is incorrect too. Fan is on left side of this 
notebook, not right as reported by driver.

It is possible to fix these problems?
