From 2d45771e6ea79f56a7d85e448f702f60ef86c228 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sun, 24 Sep 2006 20:52:15 +0200 Subject: hwmon: Add individual alarm files to 4 drivers hwmon: Add individual alarm files to 4 drivers Add individual sysfs files for all f71805f, lm63, lm83 and lm90 alarm and fault conditions. This is a requirement for the planned chip-independent libsensors. Almost all other hwmon drivers will need the same improvement.
