Pull hwmon updates from Guenter Roeck:
"New driver for INA219 and INA226, added support for IT8782F and
IT8783E/F to it87 driver, plus cleanups in a couple of drivers."
* tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging:
hwmon: (it87) Make temp3 attribute conditional for IT8782F
hwmon: (it87) Convert to use devm_kzalloc and devm_request_region
hwmon: INA219 and INA226 support
hwmon: (it87) Create voltage attributes only if voltage is enabled
hwmon: (ntc_thermistor) Fix checkpatch warning
hwmon: (ntc_thermistor) Optimize and fix build warning
hwmon: (ntc_thermistor) Return error code from hwmon_device_register
hwmon: (ntc_thermistor) Convert to devm_kzalloc
hwmon: (ad7314) Remove unused defines, and rename OFFSET to SHIFT
acpi_power_meter: clean up code around setup_attrs
acpi_power_meter: drop meter_rw_attrs, use common meter_attrs
acpi_power_meter: remove duplicate code between register_{ro,rw}_attrs
acpi_power_meter: use a {RW,RO}_SENSOR_TEMPLATE macro to clean things up
acpi_power_meter: use the same struct {rw,ro}_sensor_template for both
hwmon: use module_pci_driver
