From 6c42c30a3d4535be17fe50be6fa549bd95dd415f Mon Sep 17 00:00:00 2001 From: Sinclair Yeh Date: Wed, 29 Jun 2016 12:58:49 -0700 Subject: drm/ttm: Make ttm_bo_mem_compat available commit 94477bff390aa4612d2332c8abafaae0a13d6923 upstream. There are cases where it is desired to see if a proposed placement is compatible with a buffer object before calling ttm_bo_validate().
