From fa5f9b5aff2279d6304a8b197e12714934025575 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Tue, 19 Jan 2021 14:12:19 +0200 Subject: ACPI: Declare GNVS variables globally MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is a common place where acpigen generates these, so the declarations for the OperationRegions should be centralized too.
