From 8e6de75bd1d6fa84c4338f6e2276eb2bc339f5c9 Mon Sep 17 00:00:00 2001 From: Emily Deng Date: Mon, 8 Aug 2016 11:31:13 +0800 Subject: [PATCH] drm/amdgpu: Initialize dce_virtual_display_funcs. For virtual display feature, initialize dce_virtual_display_funcs, which will be used in function dce_virtual_set_display_funcs.
