From 3d6f99ca00ccf861305fd8630a21f2e696886708 Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Wed, 18 Jul 2007 23:45:46 -0300 Subject: ACPI: thinkpad-acpi: make EC-based thermal readings non-experimental Reading the 16 thermal sensors directly from the EC has been stable for about one year, in all supported ThinkPad models. Remove its "experimental" label.
