The PDF files that contain media images were actually generated
offline from their SVG or PNG source files.
Sphinx can handle PNG sources automatially. So, let's just
drop their PDF counterparts.
For SVG, however, Sphinx doesn't produce the right tags to
use the TexLive SVG support. Also, the SVG support is done via
shell execution, with is not nice.
So, while we don't have any support for SVG inside Sphinx
core or as an extension, move the logic to build them to Makefile,
producing the PDF images on runtime.
NOTE: due to the way Sphinx works, the PDF images should be
generated inside the Kernel source tree, as otherwise Sphinx
won't find it, not obeying what's specified by "O=" makefile
parameter.

PDF build on Kernel 4.9-rc? returns an error with Sphinx 1.3.x

LaTeX preamble and bind it to just the Sphinx versions where the
error is known to be present.

The CEC_MSG_INITIATE_ARC message is special since it is the ONLY
CEC message that accepts two possible valid replies:
CEC_MSG_REPORT_ARC_INITIATED and CEC_MSG_REPORT_ARC_TERMINATED.
So if the transmitted message is CEC_MSG_INITIATE_ARC and the remote
side replied with CEC_MSG_REPORT_ARC_INITIATED or CEC_MSG_REPORT_ARC_TERMINATED,
then a msg->reply value of CEC_MSG_REPORT_ARC_INITIATED or
CEC_MSG_REPORT_ARC_TERMINATED will match either reply.
I thought about either adding a second reply2 field, but that's ugly
for all other messages that have only one reply, and what if in the
future a new message is added that can have three replies?
Another option would be to add a cec_msg flag, but really, the combination
of CEC_MSG_REPORT_ARC_INITIATED and a reply value of one of the two
possible replies already functions as a flag.
Another advantage of this approach is that it is safe to re-use a
cec_msg struct. No need to zero a flags field or a reply2 field.
So since this really is an exception in the CEC specification, I
decided to implement it as an exception as well.

By default the CEC_MSG_USER_CONTROL_PRESSED/RELEASED messages
are passed on to the follower(s) only. If the new
CEC_LOG_ADDRS_FL_ALLOW_RC_PASSTHRU flag is set in the
flags field of struct cec_log_addrs then these messages are also
passed on to the remote control input subsystem and they will appear
as keystrokes.
This used to be the default behavior, but now you have to explicitly
enable it. This is done to force the caller to think about possible
security issues (e.g. if these messages are used to enter passwords).

Don't try to cross-reference the legacy ones.

Fix those warnings:
Documentation/media/uapi/cec/cec-ioc-dqevent.rst:124: WARNING: c:func reference target not found: clock_gettime(2)
By replacing it with the right function name, using this shell script:
for i in `find Documentation/media -type f`; do sed 's,clock_gettime(2),clock_gettime,' <$i >a && mv a $i; done
Please notice that this will make the nitpick mode to shut up
complaining about that, becasue clock_gettime is on its exclude list,
but the cross reference will be undefined until someone documents
this function at the core documentation.

The :c:type: references point to the structure name, and not to
struct foo.
Fixed via this shell script:
for i in `find Documentation/media -type f`; do perl -ne 'if (s/\:c\:type\:\`struct\s*(\S+)\`/struct :c:type:`$1`/) { s/struct\s+struct/struct/; s/(struct\s+\:c\:type\:\`\S+\`)\s+structure/$1/; } print $_' <$i >a && mv a $i; done

Instead of using c:type:`struct foo <foo>`, use:
struct c:type:`foo`
This patch was generated via this shell script:

Trivially fix those broken references, by copying the structs
fron the header, just like other API documentation at the
DVB side.
This doesn't have the level of quality used at the V4L2 side
of the API, but, as this documents a deprecated API, used
only by av7110 driver, it doesn't make much sense to invest
time making it better.

Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
There are no descriptions at ca.h header for this struct.
Yet, as we want to get rid of the warnings, let's add a
boilerplate, with just the struct types and fields.

The V4L version 1 structures had long gone from the Linux Kernel.
It doesn't make sense to use cross-references for them, as they
won't be found.
So, get rid of them.

instead of declaring the uAPI structs using usual refs, e. g.:
.. _foo-struct:
Use the C domain way:
.. c:type:: foo_struct
This way, the kAPI documentation can use cross-references to
point to the uAPI symbols.
That solves about ~100 undefined warnings like:
WARNING: c:type reference target not found: foo_struct
