Subject: [PATCH] hwmon/pc87360 separate alarm files - add
therm-min/max/crit-alarms
Adds therm-min/max/crit-alarm callbacks, sensor-device-attribute
declarations, and refs to those new decls in the macro used to
initialize the therm_group (of sysfs files)
The thermistors use voltage channels to measure; so they don't
have a fault-alarm, but unlike the other voltages, they do have an
overtemp, which we call crit (by convention).
