Hi Dan,
good catch, except that the array size of data->temp[] should be 5, not 4.
So the real culprit is commit 7cbbd6a (Add support for critical low/high
temperature limits on NCT6106) which increased the size of reg_temp but not the
size of temp.
Do you want to send me a patch fixing that, or should I take care of it ?
Thanks,
Guenter
