Add helper function to mmap ttm bo's using &drm_gem_object_funcs.mmap(). Note that with this code path access verification is done by drm_gem_mmap() (which calls drm_vma_node_is_allowed(()). The &ttm_bo_driver.verify_access() callback is is not used. v3: use ttm_bo_mmap_obj instead of ttm_bo_mmap_vma_setup Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20191016115203.20095-9-kraxel@redhat.com
