From 9d0914468fdf66d61a57e7c074b17a28eed4d3dd Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sat, 24 Oct 2009 13:28:46 +0200 Subject: [PATCH] hwmon: (dme1737) No vid attributes for SCH311x The SCH311x chips do not have VID inputs, so the cpu0_vid and vrm attributes shouldn't be created for them.
