From 06a2fe22796d9497a35778acc0becb073b242e35 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Wed, 29 Jun 2016 16:09:20 +0100 Subject: [PATCH] drm/i915: Consolidate write_tail vfunc initializer Introduce a function which initializes vfuncs mostly common across engines and move write_tail initialization in it since only one engine overrides the default.
