2020-10-15docs: get rid of :c:type explicit declarations for structsMauro Carvalho Chehab
The :c:type:`foo` only works properly with structs before Sphinx 3.x. On Sphinx 3.x, structs should now be declared using the .. c:struct, and referenced via :c:struct tag. As we now have the automarkup.py macro, that automatically convert: struct foo into cross-references, let's get rid of that, solving several warnings when building docs with Sphinx 3.x.

2020-09-30media: v4l2-subdev.rst: get rid of a duplicatd kernel-doc markupMauro Carvalho Chehab
There are two kernel-doc markups for include/media/v4l2-async.h, one at v4l2-async.rst and another one at v4l2-subdev.rst. Sphinx 3.x checks it and complains for duplicated symbols. So, get rid of one of them. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-09-27media: docs: v4l2-subdev: move calling ops to a subsectionLuca Ceresoli
Documentation on how to call the subdev ops is currently in the middle of synchronous and asynchronous registration. Move it to a dedicated subsection after the registration methods. Also move the final paragraph "The advantage of using v4l2_subdev..." to the beginning of the new section as it has an introductory content.

2020-09-27media: docs: v4l2-subdev: move "Subdev registration" to a subsectionLuca Ceresoli
The subdev registration topic is pretty lengthy, and takes more than half of the "V4L2 sub-devices" section. Help readers in finding their way through the document by dedicating a subsection to "Subdev registration". Each of the two registration methods takes many paragraphs, but since adding a subsubsection would be overkill, just emphasize them in bold.
