From 1a20d409c874255086e2f42a729826d490294c91 Mon Sep 17 00:00:00 2001 From: Ulrich Huber Date: Tue, 24 Aug 2021 14:57:44 +0200 Subject: ACPI: button: Add DMI quirk for Lenovo Yoga 9 (14INTL5) The Lenovo Yoga 9 (14INTL5)'s ACPI _LID is bugged: After hibernation the lid is initially reported as closed. Once closing and then reopening the lid reports the lid as open again. This leads to the conclusion that the initial notification of the lid is missing but subsequent notifications are correct. In order fo the Linux LID code to handle this device properly the lid_init_state must be set to ACPI_BUTTON_LID_INIT_OPEN. Signed-off-by: Ulrich Huber Signed-off-by: Rafael J.
