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" * tag 'docs-4.15' of git://git.lwn.net/linux: (52 commits) documentation: fb: update list of available compiled-in fonts MAINTAINERS: update DMAengine documentation location dmaengine: doc: ReSTize pxa_dma doc dmaengine: doc: ReSTize dmatest doc dmaengine: doc: ReSTize client API doc dmaengine: doc: ReSTize provider doc dmaengine: doc: Add ReST style dmaengine document ftrace/docs: Add documentation on how to use ftrace from within the kernel bug-hunting.rst: Fix an example and a typo in a Sphinx tag scripts: Add a script to find unused documentation samples: Convert timers to use timer_setup() documentation: kernel-api: add more info on bitmap functions Documentation: fix selftests related file refs Documentation: fix ref to power basic-pm-debugging Documentation: fix ref to trace stm content Documentation: fix ref to coccinelle content Documentation: fix ref to workqueue content Documentation: fix ref to sphinx/kerneldoc.py Documentation: fix locking rt-mutex doc refs docs: dev-tools: correct Coccinelle version number ...
