Merge tag 'docs-4.15' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"A relatively calm cycle for the docs tree again.
- The old driver statement has been added to the kernel docs.
- We have a couple of new helper scripts. find-unused-docs.sh from
Sayli Karnic will point out kerneldoc comments that are not actually
used in the documentation. Jani Nikula's
documentation-file-ref-check finds references to non-existing files.
- A new ftrace document from Steve Rostedt.
- Vinod Koul converted the dmaengine docs to RST
Beyond that, it's mostly simple fixes.
This set reaches outside of Documentation/ a bit more than most. In
all cases, the changes are to comment docs, mostly from Randy, in
places where there didn't seem to be anybody better to take them"
