From a157d06d4d70318a0818552095071d7430dd5d34 Mon Sep 17 00:00:00 2001 From: Gong Jun Date: Mon, 30 Mar 2009 21:46:43 +0200 Subject: hwmon: (w83627ehf) Only expose in6 or temp3 on the W83667HG The pin for in6 and temp3 is shared on the W83667HG, so only one of these features can be supported on any given system. Let the driver select which one depending on the temp3 disabled bit.
