The name of the subsystem is "media", and not "linux_tv". Also, as we plan to add other stuff there in the future, let's rename also the media uAPI book to media_uapi, to make it clearer. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

Description
|
|
===========
|
|
|
|
WARNING: This is a very obscure legacy command, used only at stv0299
|
|
driver. Should not be used on newer drivers.
|
|
|
|
It provides a non-standard method for selecting Diseqc voltage on the
|
|
frontend, for Dish Network legacy switches.
|
|
|
|
As support for this ioctl were added in 2004, this means that such
|
|
dishes were already legacy in 2004.
|
|
|
|
|
|
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.
