From cf6eae0facc6022d642b3588517f93c088a75bfe Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 10 Mar 2022 14:47:12 +0100 Subject: [PATCH] Revert "ACPI: PM: s2idle: Cancel wakeup before dispatching EC GPE" This reverts commit 4287509b4d21e34dc49266c6239920811e189e40 which is commit dc0075ba7f387fe4c48a8c674b11ab6f374a6acc upstream. It's been reported to cause problems with a number of Fedora and Arch Linux users, so drop it for now until that is resolved.
