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"
