From 39dabecd991b0a914f044af5824774825fb0923e Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Thu, 17 Mar 2016 13:04:10 +0000 Subject: [PATCH] drm/i915: Use shorter route to dev_private where possible Where we have a request we can use req->i915 directly instead of going through the engine and device.
