linux-next: build failure in final build

[Mark Brown]

Hi all,

During the final builds, today's linux-next build (arm64 allyesconfig)
failed like this:

error: aborting due to 3 previous errors

Some errors have detailed explanations: E0277, E0405.  For more
information about an error, try `rustc --explain E0277`.

Presumably caused by one of these commits:

  442ba16a5a513 (rust: gem: Introduce DriverObject::Args)
  e64b9cc293ae7 (rust: drm: Add gem::impl_aref_for_gem_obj!)

I have ignored this for today.
