Subject: [PATCH 08/13] hwmon: (nct6775) Separate fan/pwm configuration detection for NCT6793D
Date: Thu, 20 Sep 2018 06:45:36 -0700
Message-ID: <1537451141-27242-8-git-send-email-linux@roeck-us.net> (raw)
In-Reply-To: <1537451141-27242-1-git-send-email-linux@roeck-us.net>

While detecting the configuration for multiple chips in one go reduces
code size, it also increases code complexity. Separate chip detection
to improve code readability. As first step, separate detection for
NCT6793D.

No functional change.
