From dd2bc3f819ecb64a07f37c2a63621ecadd6b6ed8 Mon Sep 17 00:00:00 2001 From: Vladimir Serbinenko Date: Fri, 31 Oct 2014 09:16:31 +0100 Subject: igd.asl rewrite Old igd.asl had inconsistent addresses (between _DOD and actual device) and ghost devices. Any of those is enough to make brightness on windows fail and make igd.asl out-of-ACPI-spec. Also old code favoured ridiculous copying of the same thing 6 times per chipset. Leave only hooking up and chipset-specific part in chipset directory. Move NVS handling and ACPI-spec parts to a common file.
