From 5314f5c1abf03a56c6607ddef96b7a5607bee2f8 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Mon, 22 Oct 2007 17:46:17 +0200 Subject: [PATCH] hwmon: (gl518sm) Don't create sysfs files for missing features The early revisions of the GL518SM do not report voltage values for the first 3 voltage channels. We should not create sysfs attributes for these missing features. Signed-off-by: Jean Delvare Signed-off-by: Mark M.
