Changes in v5:
- Squashed subsequent fixes of three patches into one patch.
Changes in v4:
- Fix the incorrect return value of case hwmon_fan_min in function "nct7904_write_fan".
- Fix the confused calculation of case hwmon_fan_min in function
Changes in v3:
- Squashed subsequent fixes of patches into one patch.
-- Fix bad fallthrough in various switch statements.
-- Fix the wrong declared of tmp as u8 in nct7904_write_in, declared tmp to int.
-- Fix incorrect register setting of voltage.
-- Fix incorrect register bit mapping of temperature alarm.
-- Fix wrong return code 0x1fff in function nct7904_write_fan.
-- Delete wrong comment in function nct7904_write_in.
-- Fix wrong attribute names for temperature.
-- Fix wrong registers setting for temperature.
Changes in v2:
- Fix bad fallthrough in various switch statements.
- Fix the wrong declared of tmp as u8 in nct7904_write_in, declared tmp to int.
