Hi Jon,

I have a large list of patches this time for the Documentation/. So, I'm
starting sending them a little earier. Yet, those are meant to be applied
after the end of the merge window. They're based on today's linux-next,
with has only 49 patches pending to be applied upstream touching
Documentation/, so I don't expect much conflicts if applied early at
-rc cycle.

Most of the patches here were already submitted, but weren't
merged yet at next. So, it seems that nobody picked them yet.

In any case, most of those patches here are independent from 
the others.

The number of doc build warnings have been rising with time.
The main goal with this series is to get rid of most Sphinx warnings
and other errors.

Patches 1 to 5: fix broken references detected by this tool:

        ./scripts/documentation-file-ref-check

The other patches fix other random errors due to tags being
mis-interpreted or mis-used.

You should notice that several patches touch kernel-doc scripts.
IMHO, some of the warnings are actually due to kernel-doc being
too pedantic. So, I ended by improving some things at the toolset,
in order to make it smarter. That's the case of those patches:

	docs: scripts/kernel-doc: accept blank lines on parameter description
	scripts: kernel-doc: accept negation like !@var
	scripts: kernel-doc: proper handle @foo->bar()

The last 4 patches address problems with PDF building.

The first one address a conflict that will rise during the merge
window: Documentation/media will be removed. Instead of
just drop it from the list of PDF documents, I opted to drop the
entire list, as conf.py will auto-generate from the sources:

	docs: LaTeX/PDF: drop list of documents

Also, right now, PDF output is broken due to a namespace conflict 
at I2c (two pdf outputs there will have the same name).

	docs: i2c: rename i2c.svg to i2c_bus.svg

The third PDF patch is not really a fix, but it helps a lot to identify
if the build succeeded or not, by placing the final PDF output on
a separate dir:

	docs: Makefile: place final pdf docs on a separate dir

Finally, the last one solves a bug since the first supported Sphinx
version, with also impacts PDF output: basically while nested tables
are valid with ReST notation, the toolset only started supporting
it on PDF output since version 2.4:

	docs: update recommended Sphinx version to 2.4.4

PS.: Due to the large number of C/C, I opted to keep a smaller
set of C/C at this first e-mail (only e-mails with "L:" tag from
MAINTAINERS file).

* [PATCH 04/35] docs: fix broken references for ReST files that moved around

Some broken references happened due to shifting files around
and ReST renames. Those can't be auto-fixed by the script,
so let's fix them manually.
