From 6ba71de5f81bbf639b5dcea2bc2c33cdb87ed782 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Fri, 4 Nov 2011 12:00:47 +0100 Subject: hwmon: (w83627ehf) Clean up probe function The probe function has grown pretty large, I think it's time for some cleanups, starting with these two simple ones: * Move temp3/in6 check for the W83667HG later in the function, where it is done for all other chip types. * Move temperature register setting to a separate function, to avoid code duplication.
