rust: allow Rust 1.87.0's `clippy::ptr_eq` lint
commit a39f3087092716f2bd531d6fdc20403c3dc2a879 upstream.
Starting with Rust 1.87.0 (expected 2025-05-15) [1], Clippy may expand
the `ptr_eq` lint, e.g.:
error: use `core::ptr::eq` when comparing raw pointers
--> rust/kernel/list.rs:438:12
|
438 | if self.first == item {
| ^^^^^^^^^^^^^^^^^^ help: try: `core::ptr::eq(self.first, item)`
|
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#ptr_eq
= note: `-D clippy::ptr-eq` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(clippy::ptr_eq)]`
It is expected that a PR to relax the lint will be backported [2] by
the time Rust 1.87.0 releases, since the lint was considered too eager
(at least by default) [3].
Thus allow the lint temporarily just in case.
Cc: stable@vger.kernel.org # Needed in 6.12.y and later (Rust is pinned in older LTSs).

[ Converted to `allow`s since backport was confirmed. - Miguel ]
