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

Pull hwmon updates from Guenter Roeck:
 "Add support for Kaveri CPUs to k10temp driver.  Add support for S12x0
  to coretemp driver.

  Cleanup and minor fixes in several drivers.  Notable are 'Do not
  return -EAGAIN for low temperatures' to coretemp and 'Re-enable
  logical device mapping for NCT6791 during resume' to nct6775.  Both
  will be sent to -stable, but only after some time in mainline"
