The v4l2_subdev_link_validate_get_format() function warns if the pad
given as argument belongs to a non-subdev entity. This can't happen, as
the function is called from v4l2_subdev_link_validate() only (indirectly
through v4l2_subdev_link_validate_locked()), and that function ensures
that both ends of the link are subdevs.

At some point I also wondered why we need to check for non-subdev
entity. But, it was there already, so I left it...
