Merge tag 'hwmon-for-linus-v4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull hwmon fixes from Guenter Roeck:
"Two fixes headed for stable:
- Remove an unnecessary speed_index lookup for thermal hook in the
gpio-fan driver. The unnecessary speed lookup can hog the system.
- Handle negative conversion values correctly in the ads1015 driver"
* tag 'hwmon-for-linus-v4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging:
hwmon: (gpio-fan) Remove un-necessary speed_index lookup for thermal hook
hwmon: (ads1015) Handle negative conversion values correctly
