[RFCv3 PATCH 0/2] Add VIDIOC_SUBDEV_QUERYCAP

[Hans Verkuil <hverkuil@xs4all.nl>]

From: Hans Verkuil <hans.verkuil@cisco.com>

This patch series adds the VIDIOC_SUBDEV_QUERYCAP ioctl for v4l-subdev devices
as discussed during the ELC in San Jose and as discussed here:

http://www.spinics.net/lists/linux-media/msg88009.html

This patch series returns to the v1 patch series, but it drops the pads field
and the VIDIOC_QUERYCAP changes.

This should hopefully make this a minimal uncontroversial implementation that
I can finally start using in the v4l2-compliance utility.

Ideally I'd like to have a link back to the media controller, which is what
the v2 patch series was all about, but not everyone agrees so I will probably
require that when v4l2-compliance is called for a v4l-subdev node you also
have to provide the MC device node.

Regards,

	Hans
