From 6e6bc5f6e6eced5d820342db3f00d3404ce08936 Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Tue, 24 Apr 2018 16:56:03 -0300 Subject: [PATCH] platform/x86: thinkpad_acpi: silence HKEY 0x6032, 0x60f0, 0x6030 Demote to debug level one existing thermal-control related event, and also add two new ones that would otherwise trigger unknown event warnings. These events are Windows-only for now. We do report them to userspace in case they become useful in the future.
