Subject: Do not assign non-existing over-temperature and hysteresis registers
X-Git-Tag: nct6775-v1.0^0
X-Git-Url: https://git.sur5r.net/?p=groeck-nct6775;a=commitdiff_plain;h=41327efd212f93683f6f107e33bc7e4cb8e6be42

Do not assign non-existing over-temperature and hysteresis registers

Overtemperature and hysteresis registers only exist for primary
temperature registers, not for alternates.
