From a8bacec09352b86bd389cc93a20008577fa14764 Mon Sep 17 00:00:00 2001 From: Colin Leroy Date: Wed, 25 May 2005 12:31:34 -0700 Subject: [PATCH] Make sure therm_adt746x only handles known hardware This patch limits therm_adt746x to currently existing fan controllers in Apple laptops. It may avoid problems with future hardware.
