These drivers are still v4l1:


Some of these have counterparts in gspca these days so possibly some drivers
can be removed by now. Hans, can you point those out?

arv, bw-qcam, c-qcam, cpia_pp and stradis can probably be moved to staging
and if no one steps up then they can be dropped altogether.

According to my notes I should be able to test cpia_usb. I would have to
verify that, though. I think it is only used in a USB microscope. It is
effectively a webcam. I can also test usbvideo (USB 1 TV capture device).
The latter is probably the most important driver that needs converting,
because I think these are not uncommon.

However, I have no time to work on such a driver conversion. But if someone
is seriously willing to put time and effort in that, then I am willing to
mail the hardware.

To my knowledge the usbvideo driver is probably the least obscure device
that is still using V4L1.
