Subject: [PATCH 1/2] hwmon: (nct6775) Set weight source to zero correctly
Date: Wed, 05 Sep 2018 07:46:27 +0000 [thread overview]
Message-ID: <20180905074627.putclq3777lmxvoe@kili.mountain> (raw)
In-Reply-To: <df45855d-e21c-9b29-d661-7284453241fe@roeck-us.net>
This is dead code because j can never be 1 at this point. We had
intended to just test if the bit was clear.
Fixes: bbd8decd4123 ("hwmon: (nct6775) Add support for weighted fan control")
