From ad3c558fb92f725858494f6b3f0befcd89cbb41c Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Mon, 13 Jul 2015 16:30:26 +0200 Subject: [PATCH] drm/i915: Get rid of unused transitional members. The previous commit converted hw readout to atomic, all the new_* members were used for restoring the old state, but with the conversion of suspend to atomic there's no use left for them.
