Subject: [PATCH v2 03/13] rust: allow `dead_code` for never constructed bindings
Starting with the upcoming Rust 1.80.0 (since upstream commit 35130d7233e9
("Detect pub structs never constructed and unused associated constants
in traits")), the `dead_code` pass detects more cases, which triggers
in the `bindings` crate:
warning: struct `boot_params` is never constructed
--> rust/bindings/bindings_generated.rs:10684:12
|
10684 | pub struct boot_params {
| ^^^^^^^^^^^
|
= note: `#[warn(dead_code)]` on by default
As well as in the `uapi` one:
warning: struct `boot_params` is never constructed
--> rust/uapi/uapi_generated.rs:10392:12
|
10392 | pub struct boot_params {
| ^^^^^^^^^^^
|
= note: `#[warn(dead_code)]` on by default
These are all expected, since we do not use all the structs in the
bindings that `bindgen` generates from the C headers.
Therefore, allow them.
