Merge tag 'hwmon-for-v5.17-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging

Pull hwmon fixes from Guenter Roeck:
 "Fix two old bugs and one new bug in the hwmon subsystem:

   - In pmbus core, clear pmbus fault/warning status bits after read to
     follow PMBus standard

   - In hwmon core, handle failure to register sensor with thermal zone
     correctly

   - In ntc_thermal driver, use valid thermistor names for Samsung
     thermistors"
