drm/ttm: Make ttm_bo_mem_compat available
There are cases where it is desired to see if a proposed placement is compatible with a buffer object before calling ttm_bo_validate(). Signed-off-by: Sinclair Yeh <syeh@vmware.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com> Cc: <stable@vger.kernel.org> --- This is the first of a 3-patch series to fix a black screen issue observed on Ubuntu 16.04 server.
