From 26befef00eb2ae37939a189a5d03c4c7b600e6f9 Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Tue, 14 Nov 2017 17:14:14 +0100 Subject: platform/x86: thinkpad_acpi: Accept flat mode for type 4 multi mode status On the X1 Yoga 2nd Generation and most likely other notebooks the FLAT mode is reported. Decode it correctly rather than warning about an unexpected multi mode status to be reported.
