[PATCH] hwmon: Do not forcibly enable via686a by default
Do not enable the VIA VT82C686A/B integrated sensors by default, as disabled sensors usually means that this feature is not used so the values won't make any sense. This has been confusing many users in the past: http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=1786 http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=1811 http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=2052 It is still possible to forcibly enable the sensors by using the force_addr module parameter.
