Subject: [PATCH 4.1 069/267] [media] saa7164: fix querycap warning

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans Verkuil <hverkuil@...all.nl>

commit 534bc3e2ee93835badca753bedce8073c67caa92 upstream.

Fix the VIDIOC_QUERYCAP warning due to the missing device_caps. Don't fill
in the version field, the V4L2 core will do that for you.
