The conversion added an empty column (probably, it was used on
DocBook just to increase spacing.

It also added an extra line on one of the texts, breaking

The right way to use it seems to do suscript is to use
this pattern: "\ :sub:"

Make sure all places of the media document will fit, by
using this script:

$n=0;
while (<>) {
	$n++;
	$t = $_;
	@matches = $t =~ m/(..\:sub\:)/g;
	foreach my $m (@matches) {
		$m =~ m/(.)(.)(\:sub\:)/;
		$s1=$1;
		$s2=$2;
		$s3=$3;
		next if (($s1 eq "\\") && ($s2 eq " "));
		if ($s2 eq " ") {
			$t =~ s/$s1$s2$s3/$s1\\$s2$s3/;
			next;
		}
		$t =~ s/$s1$s2$s3/$s1$s2\\ $s3/;
	}
	print $t;
}

And running it with:

for i in $(git grep -l sub Documentation/linux_tv/); do ./sub.pl $i >a && mv a $i; done

Finally, a space is required before :sub:, as otherwise it

The conversion script added some comments at the end.

They'll be forever stored at the Kernel tree. So, if

The asterisks cause parsing warnings with Sphinx:

	/devel/v4l/patchwork/Documentation/linux_tv/media/dvb/fe_property_parameters:993: WARNING: Inline emphasis start-string without end-string.

On the first warning, the ISDB-T layer enabled description is a
kind of ackward. Improve it.

For the second one, IMHO, it is clearer to use [A-C], as it
shows what are the real possibilities, than using asterisk.

On several places, instead of using references, the code was

All error codes should be const. Most are, but there are
lots of places where we forgot to add <constant> at the DocBook.

Fix those via this small script:
	for i in $(git grep -lE "\s+E[A-Z]+\b" Documentation/linux_tv/); do perl -ne 's,([^\`])\b(E[A-Z]+)\b,\1``\2``,g; print $_' <$i >a && mv a $i; done

As there are false positives, we needed to merge only the changes
that make sense, skipping the c blocks and skipping things like
EDID, EN, ETS that were also converted by the above code.

On the example captions, use always <chapter>.<number>., because:
