From fd3bd0a99cffffe476d54edd2eb13b52b1e9a27d Mon Sep 17 00:00:00 2001 From: Changbin Du Date: Thu, 6 Apr 2017 10:56:03 +0800 Subject: [PATCH] drm/i915/gvt: use directly assignment for structure copying Let c compiler handle the structure copying. The compiler will use builtin function to handle that.
