[PATCH v2 00/33] Documentation fixes for Kernel 5.8

[PATCH v2 00/33] Documentation fixes for Kernel 5.8

[Mauro Carvalho Chehab]

Patches 1 to 5 contain changes to the documentation toolset:

- The first 3 patches help to reduce a lot the number of reported
  kernel-doc issues, by making the tool more smart.

- Patches 4 and 5 are meant to partially address the PDF
  build, with now requires Sphinx version 2.4 or upper.

The remaining patches fix broken references detected by
this tool:

        ./scripts/documentation-file-ref-check

and address other random errors due to tags being mis-interpreted
or mis-used.

They are independent each other, but some may depend on
the kernel-doc improvements.

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).

Jon,

Those patches should apply cleanly at docs-next, once you
pull from v5.7-rc1.


-

v2:

- patches re-ordered;
- added reviewed/acked-by tags;
- rebased on the top of docs-next + v5.7-rc1.

[PATCH v2 18/33] docs: spi: spi.h: fix a doc building warning

[Mauro Carvalho Chehab]

We need to add a blank line to avoid this warning:

	./include/linux/spi/spi.h:401: WARNING: Unexpected indentation.

I thought I'd acked this previously?

OK, I've applied this set, minus #17 which was applied elsewhere.
