From 41c4eb5fa686431f9831f337de5e9f3895633d56 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Mon, 30 Mar 2020 19:20:54 -0500 Subject: [PATCH] nb/intel/haswell: Simplify GMA SSDT generator Simplify generation of GMA SSDT, using updated naming convention. If acpi_fill_ssdt is being invoked, then we know the IGD device is present and enabled, so we can skip those checks. And the SSDT generator now checks that the gfx struct is populated, so we can skip that too.
