95a0bd5d79 docs: cec: show broken xrefs and show TOC instead of cec.h content
Enable xref broken warnings. While here, change the output to
only show cross-references, as there's no need to show the entire cec.h
header at the docs.

ee2fe81cdc Merge tag 'docs-6.18' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
 "It has been a relatively busy cycle in docsland, with changes all
  over:

   - Bring the kernel memory-model docs into the Sphinx build in the
     "literal include" mode.

   - Lots of build-infrastructure work, further cleaning up long-term
     kernel-doc technical debt. The sphinx-pre-install tool has been
     converted to Python and updated for current systems.

   - A new tool to detect when documents have been moved and generate
     HTML redirects; this can be used on kernel.org (or any other site
     hosting the rendered docs) to avoid breaking links.

   - Automated processing of the YAML files describing the netlink
     protocol.

   - A significant update of the maintainer's PGP guide.

  ... and a seemingly endless series of typo fixes, build-problem fixes,
  etc"

8a298579cd scripts: sphinx-build-wrapper: get rid of uapi/media Makefile
Now that kernel-include directive supports parsing data
structs directly, we can finally get rid of the horrible hack
we added to support parsing media uAPI symbols.

As a side effect, Documentation/output doesn't have anymore
media auto-generated .rst files on it.

613f21505b media: cec: core: add new CEC_MSG_FL_REPLY_VENDOR_ID flag
If this flag is set, then the reply is expected to consist of
the CEC_MSG_VENDOR_COMMAND_WITH_ID opcode followed by the Vendor ID (as
used in bytes 1-4 of the message), followed by the struct cec_msg reply
field.

Note that this assumes that the byte after the Vendor ID is a
vendor-specific opcode.

This flag makes it easier to wait for replies to vendor commands,
using the same CEC framework support for waiting for regular replies.

Support for this flag is indicated by setting the new
CEC_CAP_REPLY_VENDOR_ID capability.

dd05fd125e media: cec: return -ENODEV instead of -ENXIO if unregistered
If the CEC device is unregistered, then an attempt to open
the device node should result in an -ENODEV error instead of
-ENXIO.

Document this as well in cec-func-open.rst.

This is consistent with the error code returned by other
file operations such as ioctl.

58af664644 media: doc: properly format ToC headings
"class:: toc-title" was a workaround for older Sphinx versions that are
no longer supported.

The canonical way to add a heading to the ToC is to use :caption:.
Do that.

54f38fcae5 media: docs: move uAPI book to userspace-api/media
Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee38 ("docs: Create a user-space API guide").

As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.

Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.
