Merge tag 'hwmon-for-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging

Pull hwmon updates from Guenter Roeck:
 "The big change in this series is for the most part automatic:
  Introducing SENSOR[_DEVICE]_ATTR_{RO,RW,WO} variants and conversion of
  various drivers to use it. This is similar to DEVICE_ATTR variants.

  Other than that, we have

   - Some conversions of S_<PERMS> with octal values, also automated

   - Added support for Hygon Dhyana CPUs to k10temp driver

   - Added support for STLM75 to lm75 driver

   - B57891S0103 to ntc_thermistor

   - Added pm-runtime support to ina3221 driver

   - Support for PowerPC On-Chip Controller (OCC)

   - Various minor bug fices and improvements"
