From 67167240063c9eff15d60754c8d786a7a237ffa2 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Thu, 27 Jun 2013 16:30:18 -0700 Subject: [PATCH] drm/i915: Combine scratch members into a struct There isn't any special reason to do this other than it makes it obvious that the two members are connected.
