From 4d9bf45f0d8213d72aa05799b359da9146d67781 Mon Sep 17 00:00:00 2001
From: Thomas Zimmermann <tzimmermann@suse.de>
Date: Tue, 31 Jul 2018 09:12:35 +0200
Subject: [PATCH 5034/5725] drm/amdgpu: Replace ttm_bo_reference with
ttm_bo_get
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The function ttm_bo_get acquires a reference on a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.
v2:
* changed prefix to drm/amdgpu
