Forgot to add here, but it is probably worth to show the output of
media-ctl showing the entities created on cx231xx:

$ /usr/local/bin/media-ctl -p
Media controller API version 0.1.1

Media device information
------------------------
driver          cx231xx

bus info        1.2
hw revision     0x4001
driver version  3.19.0

Device topology
- entity 1: cx25840 19-0044 (0 pad, 0 link)
            type V4L2 subdev subtype Unknown flags 0

- entity 2: tuner 21-0060 (0 pad, 0 link)
            type V4L2 subdev subtype Unknown flags 0

- entity 3: cx231xx #0 video (0 pad, 0 link)
            type Node subtype V4L flags 0
            device node name /dev/video0

PS.: I didn't patch yet the media-ctl to better enumerate the DVB devices.

Cheers,
