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

Pull hwmon updates from Guenter Roeck:
 "New drivers for DA9052/53 PMIC as well as HIH-6130/HIH-6131 humidity
  and temperature sensors.

  Convert drivers to use devm_ functions and to use dev_pm_ops.  Address
  a couple of Coverity errors/warnings as well as compile warnings.
  Some functional improvements in applesmc driver."
