Merge branch 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging 

Pull hwmon subsystem update from Jean Delvare:
 "There are many improvements to the it87 driver, as well as suspend
  support for the Winbond Super-I/O chips, and a few other fixes."

Trip points must be set properly before switching to automatic fan speed

control mode. The driver will perform basic integrity checks before

actually switching to automatic control mode.





Temperature offset attributes

-----------------------------



The driver supports temp[1-3]_offset sysfs attributes to adjust the reported

temperature for thermal diodes or diode-connected thermal transistors.

If a temperature sensor is configured for thermistors, the attribute values

are ignored. If the thermal sensor type is Intel PECI, the temperature offset

must be programmed to the critical CPU temperature.
