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 driver to support GMT G762/G763 pwm fan controllers
- add support for DS1631, DS1721, and DS1731 to ds1621 driver
- remove detect function from ds1621 driver as unreliable
- bug fixes in nct6775, iio_hwmon, and adm1021 drivers
- remove redundant platform_set_drvdata in various drivers
- add device tree support to ina2xx driver
