Patch Review

**Correctness: Good.** On drm-next, `ARef` is defined in `rust/kernel/sync/=
aref.rs` and is no longer present in or re-exported from `rust/kernel/types=
.rs`. The current code:

```rust
types::{
    ARef,
    Opaque, //
}, //
```

will indeed fail to compile. The fix changes it to:

```rust
sync::aref::ARef,
types::Opaque, //
```

This matches the convention used elsewhere in the same DRM subsystem =E2=80=
=94 `rust/kernel/drm/driver.rs:14` already imports via `sync::aref::ARef`.

**Minor nit:** The trailing `//` comment on the `types::Opaque` line is a `=
rustfmt` artifact to force one-import-per-line formatting. That's fine and =
consistent with the surrounding code style (the existing code had it too). =
No issue here, just noting it's intentional.

**Commit message:** The commit message is adequate but could be slightly mo=
re precise. It says "ARef is defined in sync and is getting used from types=
 causing the build to fail" =E2=80=94 it would be clearer to say "ARef was =
moved from `kernel::types` to `kernel::sync::aref`" to explain *why* the im=
port broke. This is a very minor suggestion and not a blocker.

**No functional concerns.** The change is purely an import path fix with no=
 behavioral impact.
