Merge tag 'docs-5.15' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"Yet another set of documentation changes:
- A reworking of PDF generation to yield better results for documents
using CJK fonts in particular.
- A new set of translations into traditional Chinese, a dialect for
which I am assured there is a community of interested readers.
- A lot more regular Chinese translation work as well.
... plus the usual assortment of updates, fixes, typo tweaks, etc"
