Pull hwmon changes for v3.4 from Guenter Roeck: "Mostly cleanup. No new drivers this time around, but support for several chips added to existing drivers: TPS40400, TPS40422, MTD040, MAX34446, ZL9101M, ZL9117M, and LM96080. Also, added watchdog support for SCH56xx, and additional attributes for a couple of drivers." * tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging: (137 commits) hwmon: (sch56xx) Add support for the integrated watchdog (v2) hwmon: (w83627ehf) Add support for temperature offset registers hwmon: (jc42) Remove unnecessary device IDs hwmon: (zl6100) Add support for ZL9101M and ZL9117M hwmon: (adm1275) Add support for ADM1075 hwmon: (max34440) Add support for MAX34446 hwmon: (pmbus) Add more virtual registers hwmon: (pmbus) Add support for Lineage Power MDT040 hwmon: (pmbus) Add support for TI TPS40400 and TPS40422 hwmon: (max34440) Add support for 'lowest' output voltage attribute hwmon: (jc42) Convert to use devm_kzalloc hwmon: (max16065) Convert to use devm_kzalloc hwmon: (smm665) Convert to use devm_kzalloc hwmon: (ltc4261) Convert to use devm_kzalloc hwmon: (pmbus) Simplify remove functions hwmon: (pmbus) Convert pmbus drivers to use devm_kzalloc hwmon: (lineage-pem) Convert to use devm_kzalloc hwmon: (hwmon-vid) Fix checkpatch issues hwmon: (hwmon-vid) Add new entries to VRM model table hwmon: (lm80) Add detection of NatSemi/TI LM96080 ...
