`needless_pass_by_value` sometimes suggest marking the concerned type as
`Copy`. Adding a `or` before this suggestion makes it clearer that this
is not the second part of the original suggestion, but an alternative one.
Not trigger `duplicated_attributes` on duplicate reasons
As at #13355 we shoudn't trigger `duplicated_attributes` on duplicate reasons attr

Special-case suggestions for null pointers constness cast
This implements the suggestions from #13361. It fits into the existing `ptr_cast_constness` lint, as this is a specialized version. However,
1. I have not modified the lint MSRV, so the documentation for this lint will still show that it applies only from Rust 1.72.0. This is true in the general case, but the lint for null pointers will trigger even before this version as `null()` and `null_mut()` were already present in Rust 1.0 and there is no reason not to apply this lint. I guess this is only a minor documentation issue that can be ignored.
2. I have not covered the `core::ptr::null::<T>().cast_mut()` (could be made into `core::ptr::null_mut::<T>()`) and `cotr::ptr::null_mut::<T>().cast_const()` (could be made into `core::ptr::null::<T>()`) cases. Should they be covered? If they should, here or in a separate PR?

Fix#13361
Bump ui_test
This should give a bunch of ui improvements when lots of tests are running. Please lmk of any issues with it. Switching to `--quiet` should always avoid any issues, so there's a workaround if anything crops up. Also please check that this does not regress performance for you. It doesn't for me, but that doesn't mean much.

Visit struct fields recursively in uninit fallback check
This makes the fallback a bit more consistent with the other checks and rustc.
Fixes#13364. When using a generic type as the `Vec` element type like the issue title says, rustc's uninit check fails and our fallback is used, which didn't look at struct fields when it could.

Extend `implicit_saturating_sub` lint
Fixes#10070.
It can serve as base if we want to add equivalent checks for other arithmetic operations.
Also one important note: when writing this lint, I realized that I could check for wrong conditions performed beforehand on subtraction and added another part in the lint. Considering they both rely on the same checks, I kept both in the same place. Not sure if it makes sense though...

Use `is_diagnostic_item` for checking a def_id in `unnecessary_min_or_max`.
close#13191
This PR fixes the false positives in `unnecessary_min_or_max `.
We should use `is_diagnostic_item` for checking def_ids in this lint.

Rewrite `empty_line_after_doc_comments` and `empty_line_after_outer_attr`, move them from `nursery` to `suspicious`
changelog: [`empty_line_after_doc_comments`], [`empty_line_after_outer_attr`]: rewrite and move them from `nursery` to `suspicious`
They now lint when there's a comment between the last attr/doc comment and the empty line, to cover the case:
```rust
/// Docs for `old_code
// fn old_code() {}
fn new_code() {}
```
When these lints or `suspicious_doc_comments` trigger we no longer trigger any other doc lint as a broad fix for #12917, reverts some of #13002 as the empty line lints cover it
I ended up not doing https://github.com/rust-lang/rust-clippy/issues/12917#issuecomment-2161828859 as I don't think it's needed
Ignore underscore-prefixed args for needless_pass_by_value lint
When a user explicitly tags a param as unused (yet?), there is no need to raise another lint on it.
fixes#7295
Note that I had to rename all `_*` params in the tests, but kept the variable name length to avoid extra changes in the expected output.

Diverging subexpression lint should not fire on todo!()
As per #10243 it is not that helpful to point out that a subexpression diverges, so do not fire on todo
