[PATCH 1/9] media: docs: v4l2-controls: fix sentence rendered in a nonsense way

[Luca Ceresoli]

This sentence renders as:

> Since such compound controls need to expose more information about
> themselves than is possible with ioctls VIDIOC_QUERYCTRL,
> VIDIOC_QUERY_EXT_CTRL and VIDIOC_QUERYMENU the VIDIOC_QUERY_EXT_CTRL
  ^^^^^^^^^^^^^^^^^^^^^                          ^^^^^^^^^^^^^^^^^^^^^
> ioctl was added.

This does not make sense. Fix by providing an explicit link text. This
results in:

> Since such compound controls need to expose more information about
> themselves than is possible with VIDIOC_QUERYCTRL and VIDIOC_QUERYMENU
> the VIDIOC_QUERY_EXT_CTRL ioctl was added.

 Since such compound controls need to expose more information about
 themselves than is possible with
-:ref:`VIDIOC_QUERYCTRL` the
+:ref:`VIDIOC_QUERYCTRL and VIDIOC_QUERYMENU <VIDIOC_QUERYCTRL>` the
 :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>` ioctl was added. In
 particular, this ioctl gives the dimensions of the N-dimensional array
 if this control consists of more than one element.
