Merge tag 'docs-5.13' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"It's been a relatively busy cycle in docsland, though more than
usually well contained to Documentation/ itself. Highlights include:
- The Chinese translators have been busy and show no signs of
stopping anytime soon. Italian has also caught up.
- Aditya Srivastava has been working on improvements to the
kernel-doc script.
- Thorsten continues his work on reporting-issues.rst and related
documentation around regression reporting.
- Lots of documentation updates, typo fixes, etc. as usual"
