Subject: [PATCH 5.4 33/33] Revert "ACPI: PM: s2idle: Cancel wakeup before dispatching EC GPE"
Date: Thu, 10 Mar 2022 15:19:34 +0100	[thread overview]
Message-ID: <20220310140809.711995140@linuxfoundation.org> (raw)
In-Reply-To: <20220310140808.741682643@linuxfoundation.org>

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This reverts commit 9d09cb110868f027d015fbc6c64ba1e45a69a192 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.
