V4L/DVB (8104): cx18/ivtv: ioctl debugging improvements
Completely rely on the video_ioctl2 debugging facilities rather than doing it ourselves. Fill in some missing fields in ivtv with VIDIOC_G_FBUF. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
