From 3d914e8357256e7e92d1b7dd2dda9cf94e39c4e8 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 8 Aug 2013 15:41:17 +0200 Subject: drm: hide legacy sg cleanup better from common code I've decided that some clear markers for what's legacy dri1/non-gem code is useful. I've opted to use the drm_legacy prefix and then hide all the checks in that function for better readability in the common code.
