Subject: [PATCH v2 15/27] media: dmx.h: get rid of GET_DMX_EVENT

This seems to be a pure fictional API :-)

It only exists at the DVB book, with no code implemeting it.

So, just get rid of it.

-Synopsis
---------
-
-.. c:function:: int ioctl( int fd, DMX_GET_EVENT, struct dmx_event *ev)
-    :name: DMX_GET_EVENT
-
-
-Arguments
----------
-
-``fd``
-    File descriptor returned by :c:func:`open() <dvb-dmx-open>`.
-
-``ev``
-    Pointer to the location where the event is to be stored.
-
-
-Description
------------
-
-This ioctl call returns an event if available. If an event is not
-available, the behavior depends on whether the device is in blocking or
-non-blocking mode. In the latter case, the call fails immediately with
-errno set to ``EWOULDBLOCK``. In the former case, the call blocks until an
-event becomes available.
-
-
-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.

-       -  ``EWOULDBLOCK``
-
-       -  There is no event pending, and the device is in non-blocking mode.
