From 38641aa8b40ef66e5a5016f6f299a3aa1fb9b0d5 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Tue, 31 Mar 2020 17:51:18 +0200 Subject: drivers/intel/gma/acpi: Bail out on empty display list Whether the GMA is used depends on the mainboard, so we shouldn't rely on the presence of the static ACPI code around `GFX0`.
