Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
type of R/W arguments. They were fixed, but the old ioctl names are
still there, maintained to avoid breaking binary compatibility:

There's no sense on preserving those forever, as it is very doubtful
that someone would try to use a such old binary with a modern kernel.
Removing them will allow us to remove some magic done at the V4L ioctl
handler.

Note that any application compiled with a videodev2.h from 2.6.7 or later
will be using the correct ioctls.

The dabusb driver was conceived as an experimental driver for a test
device. The driver never supported any shipped product, and, while
there were some updates for it in 2003, for an ancient product,
those changes were never submitted upstream.

Also, there's no DocBook for its API, nor any upstream discussion.

So it was decided to remove it in 2.6.39. Future support for a DAB API
should be discussed on the linux-media list first.

This driver is for obsolete hardware that the old maintainer
didn't care (or not have the hardware anymore), and that no other developer
could find any hardware to buy.

The V4L1 API is no longer supported, and since nobody stepped in to convert
them to V4L2 the decision was made to remove them.

With the new gspca v4l2 vicam driver, there is no more reason to keep the
old v4l1 usbvideo vicam driver around, and since that is the last
usbvideo framework using driver, the old usbvideo framework itself can
go too.

This is a complete rewrite of the old v4l1 vicam subdriver, featuring
multiple resolutions, gain + exposure control and still has less code.

Oh and it is a v4l2 driver rather then v4l1 ofcourse :)

v4l2-ctl and qv4l2 enumerate controls using V4L2_CTRL_FLAG_NEXT_CTRL,
falling back to the old method if the flag isn't supported.

The v4l2_subdev_queryctrl function will currently handle that flag, but
for the controls of the subdev only. This isn't right, it should refuse
this flag, otherwise v4l2-ctl will only see the controls of the first
subdev.

Having the device detection happening at reset is bad, as every time,
it will produce a message like:
	tvp5150 2-005c: tvp5150am1 detected.

This only polutes the log and for an accidental kernel hacker, it looks
like a real problem. So, move those printk's to happen during device
probe.
