From ca4e713080dd7f23cd1cf5d3871e0b717ee9b254 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Tue, 15 Jan 2013 23:57:16 +0100 Subject: [PATCH] ACPI / thermal: Use mode to enable/disable kernel thermal processing As per documentation, "mode" sysfs interface should be able to enable/disable thermal processing in the kernel, so that user space is able to take more control. Currently, ACPI thermal driver is not following this setting, so modify it to match the interface documentation. Signed-off-by: Srinivas Pandruvada Signed-off-by: Rafael J.
