From e91883f5459fa8e8803cb9740bcb5a2cd011a5fb Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Mon, 30 Mar 2020 22:20:03 -0500 Subject: nb/intel/gm45: 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.
