Can I desable the /dev/video creation in DART-SD410(Dragonboard410c compatible)?

I use the DART-SD410 module and its career board, that is compatible Dragonboard 410c.

and, in Debian Linaro 4.4.9,
the Device file /dev/video0 is created automatically, even though ov5645 or any sensors are not connected to CSI port.

How do I disable this ?

I’ve tried that delete node ‘camera@78’ from msm8916.dst, but it still be created…
and , I can’t found csiphy0_ep node in there…

Thanks.
