There are a number of other ioctls that aren't used anywhere
inside the Kernel tree.

Get rid of them.

-    -
-
-       -  __u64 \*pts
-
-       -  Returns the 33-bit timestamp as defined in ITU T-REC-H.222.0 /
-	  ISO/IEC 13818-1.
-
-	  The PTS should belong to the currently played frame if possible,
-	  but may also be a value close to it like the PTS of the last
-	  decoded frame or the last PTS extracted by the PES parser.
-
-
-Description
------------
-
-This ioctl is obsolete. Do not use in new drivers. If you need this
-functionality, then please contact the linux-media mailing list
-(`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__).
-
-This ioctl call asks the Audio Device to return the current PTS
-timestamp.
-
-
-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.
