Merge tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
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."
