Rust's standard library's `std::iter::Iterator` trait provides a function
`find` that finds the first element that satisfies a predicate.
The function `Version::from_segments` is doing the same thing but is
implementing the same logic itself.
Clippy complains about this in the `manual_find` lint:
error: manual implementation of `Iterator::find`
--> drivers/gpu/drm/drm_panic_qr.rs:212:9
|
212 | / for v in (1..=40).map(|k| Version(k)) {
213 | | if v.max_data() * 8 >= segments.iter().map(|s| s.total_size_bits(v)).sum() {
214 | | return Some(v);
215 | | }
216 | | }
217 | | None
| |____________^ help: replace with an iterator: `(1..=40).map(|k| Version(k)).find(|&v| v.max_data() * 8 >= segments.iter().map(|s| s.total_size_bits(v)).sum())`

Use `Iterator::find` instead to make the intention clearer.
At the same time, clean up the redundant closure that Clippy warns
about too:
error: redundant closure
--> drivers/gpu/drm/drm_panic_qr.rs:212:31
|
212 | for v in (1..=40).map(|k| Version(k)) {
| ^^^^^^^^^^^^^^ help: replace the closure with the function itself: `Version`

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
