a17a954efd [media] docs-rst: fix some broken struct references
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

fc78c7c7a1 [media] docs-rst: simplify c:type: cross references
Instead of using c:type:`struct foo <foo>`, use:
	struct c:type:`foo`

This patch was generated via this shell script:

848d10314b [media] fix broken references on dvb/video*rst
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.

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:

The SYCC Y'CbCr encoding is identical to the 601 encoding. Since the

This patch also adds a 4th decimal to the 601 conversion matrix.
That was specified by the sYCC spec and it makes sense to use this
across the board.

This is only one example, demonstrating the benefits of the patch
series.  The CEC_DQEVENT ioctl is migrated to the sphinx c-domain and
referred by ":name: CEC_DQEVENT".

With this change the indirection using ":ref:`CEC_DQEVENT` is no longer
needed, we can refer the ioctl directly with ":c:func:`CEC_DQEVENT`". As
addition in the index, there is a entry "CEC_DQEVENT (C function)".

There are two big tables here that are very hard to adjust its

The first one would fit into one page, but the latex.py logic
at Sphinx auto-switches to longtable when there are more than 30
rows. There's no way to override without coding.

The second one is really big, and won't fit on a single page.
So, it has to use tiny font to fit.

0c04622162 [media] extended-controls.rst: avoid going past page with LaTeX
It is painful to put code/verbatim code in bold. It seems that
the only way is to arrange it like:
	``foo``
	    bar

At least on LaTeX output, when this happens, the "foo" string
is not hidentable/breakable. The entire string should fit into
a single line.

Add a workaround for this ReST limitation by splitting the
foo string into two strings, on separate lines. The output
is not the best, but it works.
