Patch Review

**Status: Correct, no issues**

The change is minimal and mechanical:

1. **`file.rs` import update** =E2=80=94 Adds `TyrDrmDevice` to the import:
```rust
-use crate::driver::TyrDrmDriver;
+use crate::driver::{
+    TyrDrmDevice,
+    TyrDrmDriver, //
+};
```
`TyrDrmDriver` is still needed because the `DriverFile` impl uses `type Dri=
ver =3D TyrDrmDriver;`. The trailing `//` comment is a `rustfmt` trick to f=
orce one-item-per-line formatting =E2=80=94 this is a common Rust style con=
vention and matches the existing pattern at the top of the file (e.g., `uap=
i, //`).

2. **`file.rs` signature update** =E2=80=94 `dev_query` uses the alias:
```rust
-        ddev: &drm::Device<TyrDrmDriver>,
+        ddev: &TyrDrmDevice,
```
Correct. Note that `fn open(_dev: &drm::Device<Self::Driver>)` is intention=
ally left unchanged since it uses the associated type `Self::Driver` throug=
h the trait, which is the idiomatic pattern there.

3. **`gem.rs` import and signature update** =E2=80=94 Same pattern as `file=
.rs`:
```rust
-    fn new(_dev: &kernel::drm::Device<TyrDrmDriver>, _size: usize) -> impl=
 PinInit<Self, Error> {
+    fn new(_dev: &TyrDrmDevice, _size: usize) -> impl PinInit<Self, Error>=
 {
```
Correct. The `type Driver =3D TyrDrmDriver;` associated type is kept since =
it's required by the trait.

**Minor observation:** As mentioned above, the drm-next tree (`file.rs:3`, =
`file.rs:27`; `gem.rs:3`, `gem.rs:15`) already has this change applied with=
 the shorter names `TyrDevice`/`TyrDriver`. This patch will not apply to dr=
m-next and appears to target a different base branch. The commit message's =
rationale about "reducing diffs when multiple series are touching these fil=
es" supports this =E2=80=94 it's likely a preparatory cleanup for a feature=
 branch.

**Reviewed-by assessment:** The patch is trivially correct for its stated b=
ase. No functional concerns.
