Merge tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Couple of regressions, couple of zero-day bugs, a minor enhancement.
Nothing really major.
* tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging:
hwmon: (f75375s) Let f75375_update_device treat pwmX as a measured value
hwmon: (f75375s) Fix bit shifting in f75375_write16
hwmon: (f75375s) Fix reading of wrong register when initializing the F75387
hwmon: (f75375s) Fix automatic pwm mode setting for F75373 & F75375
hwmon: (w83627ehf) Remove duplicate code
