For the new Rust support for 32-bit arm [1], Clippy warns:
error: useless conversion to the same type: `i32`
--> rust/kernel/error.rs:139:36
|
139 | unsafe { bindings::ERR_PTR(self.0.into()) as *mut _ }
| ^^^^^^^^^^^^^ help: consider removing `.into()`: `self.0`
|
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#useless_conversion
= note: `-D clippy::useless-conversion` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(clippy::useless_conversion)]`
The `self.0.into()` converts an `c_int` into `ERR_PTR`'s parameter
which is a `c_long`. Thus, both types are `i32` in 32-bit. Therefore,
allow it for those architectures.
