Please turn the BUG_ON's into WARN_ON's. The machine won't go

Hi Guenter,
Thank you for the guidance.
But looking at the hwmon linux documentation, seems the sensor
kernel drivers should report only raw readings.
The raw readings can be converted into required output,
e.g. temperature in this case, by respective user space implementation.
"raw" means
Hi,
I have a question related to hwmon driver and need suggestions.
I am working on a temperature sensor driver that is hwmon driver.
- The temperature is calculated from raw sensor reading and
certain initialization parameters.
- Raw reading obtained from 2 different sensor instances under
same
87 matches
