You should keep this check for now. See this discussion:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg56550.html
I'm going to change v4l2-compliance to make this a warning instead of an
error for now.

After updating v4l2-compliance (I've just made the change to v4l2-compliance)
can you also post the output of v4l2-compliance for this driver?
Thanks,
Hans
