From 16d752397301b95abaa95cbaf9e785d221872311 Mon Sep 17 00:00:00 2001 From: Rene Herman Date: Tue, 24 Jun 2008 19:38:56 +0200 Subject: thermal: Create CONFIG_THERMAL_HWMON=n A bug in libsensors <= 2.10.6 is exposed when this new hwmon I/F is enabled. Create CONFIG_THERMAL_HWMON=n until some time after libsensors 2.10.7 ships so those users can run the latest kernel. libsensors 3.x is already fixed -- those users can use CONFIG_THERMAL_HWMON=y now.
