Hi Jean, Rudolf, after infiltrating the sensors user space part, I think it's time to dive into kernel space. So I took a look at some of the sensor drivers to get an understanding. Unfortunately I couldn't find a bug to fix, so I had to do something else :) I don't know whether this patch is worth to be applied, but I have to start somewhere. I'm very interested in doing more kernel stuff. So if you have some work to do, please tell me about it. Thanks Andre --- At the exit_free label in k8temp_probe() the driver data is set to NULL. This field isn't set before. So this should be done in exit_remove.
