Subject: drm/nouveau: wrap calls to ttm_bo_validate()
X-Git-Tag: v3.0~2447^2~37^2~13
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7a45d764a8e3177f0c9cd4a0be9f2ab7965e55cb;p=platform%2Fkernel%2Flinux-amlogic.git

drm/nouveau: wrap calls to ttm_bo_validate()

This will be used later to fixup bo.offset with a buffer's fixed GPU
virtual address.
