Subject: linux-next: build failure after merge of the drm-misc tree

Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:


Caused by commit

  a78a8da51b36 ("drm/ttm: replace busy placement with flags v6")

interacting with commit

  dd08ebf6c352 ("drm/xe: Introduce a new DRM driver for Intel GPUs")

(and maybe others) from Linus' tree (v6.8-rc1).

I have applied the following merge fix patch for today.  This makes it build,
but more is likely needed ...
