From 086e81f6b90e41a07a1a885bb11e93daa6915747 Mon Sep 17 00:00:00 2001 From: Thomas Weißschuh Date: Tue, 30 Nov 2021 07:01:17 +0100 Subject: HID: intel-ish-hid: ipc: only enable IRQ wakeup when requested MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes spurious wakeups from s0ix on Lenovo ThinkPad X1 Cargon Gen 9 on lid close. These wakeups are generated by interrupts from the ISH on changes to the lid status. By disabling the wake IRQ from the ISH we inhibit these spurious wakeups while keeping the resume from LID open through the ACPI interrupt. Reports on the Lenovo forums indicate that Lenovo ThinkPad X1 Yoga Gen6 is also affected.
