Name all ioctl references and make them match the ioctls that are documented. That will improve the cross-reference index, as it will have all ioctls and syscalls there. While here, improve the documentation, marking the deprecated ioctls, and making the non-deprecated ones more like the rest of the media book. Also, add a notice for ioctls that still require documentation. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

Description
|
|
-----------
|
|
|
|
This ioctl is for DVB devices only. To control a V4L2 decoder use the
|
|
V4L2 :ref:`VIDIOC_DECODER_CMD` with the
|
|
``V4L2_DEC_CMD_START_MUTE_AUDIO`` flag instead.
|
|
|
|
This ioctl call asks the audio device to mute the stream that is
|
|
currently being played.
|
|
|
|
|
|
Return Value
|
|
------------
|
|
|
|
On success 0 is returned, on error -1 and the ``errno`` variable is set
|
|
appropriately. The generic error codes are described at the
|
|
:ref:`Generic Error Codes <gen-errors>` chapter.
