From 348753379a7704087603dad403603e825422fd9a Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Tue, 8 May 2007 17:22:03 +0200 Subject: [PATCH] hwmon/w83781d: Use dynamic sysfs callbacks This lets us get rid of some of the macro-generated functions and shrinks the driver size significantly (about 9%).
