From c71d5fb717294ed9e46fc9a5855e8a1878b56f85 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Mon, 2 Aug 2021 15:05:15 +0800 Subject: x86: queensbay: Return directly if IGD / SDVO were already disabled Initialize 'igd' and 'sdvo' to NULL so that we just need to test them against NULL later, to be compatible with that case that IGD and SDVO devices were already in disabled state.
