Merge tag 'hwmon-for-linus-v4.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull hwmon fixes from Guenter Roeck: "Some late hwmon patches, all headed for -stable - fix sysfs attribute initialization in nct6775 and nct6683 drivers - do not attempt to auto-detect tmp435 on I2C address 0x37 - ensure iio channel is of type IIO_VOLTAGE in ntc_thermistor driver" * tag 'hwmon-for-linus-v4.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging: hwmon: (nct6683) Add missing sysfs attribute initialization hwmon: (nct6775) Add missing sysfs attribute initialization hwmon: (tmp401) Do not auto-detect chip on I2C address 0x37 hwmon: (ntc_thermistor) Ensure iio channel is of type IIO_VOLTAGE
