From 932e1ba486117de2fcea3df27ad8218ad6c11470 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 26 Oct 2019 22:24:34 +0200 Subject: [PATCH] ACPI: button: Add DMI quirk for Medion Akoya E2215T The Medion Akoya E2215T's ACPI _LID implementation is quite broken: 1. For notifications it uses an ActiveLow Edge GpioInt, rather then an ActiveBoth one, meaning that the device is only notified when the lid is closed, not when it is opened. 2. Matching with this its _LID method simply always returns 0 (closed) In order for the Linux LID code to work properly with this implementation, the lid_init_state selection needs to be set to ACPI_BUTTON_LID_INIT_OPEN. This commit adds a DMI quirk for this. Reviewed-by: Andy Shevchenko Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
