[PATCH v2 00/12] rust: kernel: documentation improvements

[Valentin Obst <kernel@valentinobst.de>]

This patch set aims to make small improvements to the documentation of
the kernel crate. It engages in a few different activities:
- fixing trivial typos (commit #1),
- updating code examples to better reflect an idiomatic coding style
  (commits #2,6),
- increasing the consistency within the crate's documentation as a whole
  (commits #3,5,7,8,9,11,12),
- adding more intra-doc links as well as srctree-relative links to C
  header files (commits #4,10).

---
Changes in v2:
- Drop commit "rust: kernel: add doclinks with html tags" in response to
  review.
- Fix another list item alignment issue pointed out during review of v1.
  Was added to commit "rust: kernel: fix multiple typos in
  documentation".
- Commit "rust: error: move unsafe block into function call" is now
  "rust: error: improve unsafe code in example" and also rewords the
  SAFETY comment of the code example.
  - Did not add 'Reviewed-By' tags offered in v1 tags due to changes.
- Link to v1: https://lore.kernel.org/lkml/20240116160141.165951-1-kernel@valentinobst.de/
