The code was testing an 8-bit address against a 7-bit address. Will the
confusion of the two never cease?
Biggest flaw of the I2C protocol: the R/W bit is the LSB instead of the
MSB. No one can ever agree if addresses are 7-bits and the R/W bit
follows them, or if they are 8-bit and the R/W bit is OR-ed into the
address byte. If the R/W bit was first, it wouldn't make any difference!

One bit wide bitfields need to declared unsigned to have the range 0 to
1, or they have the range -1 to 0.
A few techniques to reduce the driver's size by about 1700 bytes on ia32,
probably more on x86-64.
Put the biggest fields first, less padding is necessary that way.
Put fields with a limited range into a smaller type. For example
VideoChannels will fit in 3 bits, and TunerType can use 8 bits.
Vin_Reg1, Vin_Reg2, and Dvi_yuv define values for 8-bit registers, but
they can't just go into an 8-bit field with no changes, since -1 was used
as a flag to indicate a value was not present. So what we do is create a
one-bit flag for each one to indicate if a value is or is not present.
This only takes 9 bits and has the added advantage that when the register
isn't overridden (Vin_Reg[12] never are) it doesn't need to appear in the
structure definition since the default value for the flag will be zero.

Changed usbvision cards table to allow:
1) Not repeat USB ID on two structs;
2) Not need to specify both usb and card description tables at
the same order, removing some magic;
Some cards had duplicated names. Fixed.
A test for an specific board were doing by using a string comparation.
The comparation were wrong. Also, it is not a good practice to recognize
a board based on his string name.

The V4L2 API requires a unique bus_info string returned as part of the
v4l2_capability structure. These changes gather up the USB address
information, from the underlying device, into a string and report that
out through v4l2 and via sysfs (for completeness).

There were many places in the driver which had long sequences of constant
register initializations. These were done with one function call per
register. The register address and value were immediate values in the
function calls.
This is very inefficient, as each register and value take twice the space
when they are code, as each includes a push instruction to put it on
the stack. There there is the overhead, both size and time, for a
function call for each register. It's also quite a few lines of C code
to do this.
The patch creates a function that writes multiple registers from a list,
and a macro that makes it easy to construct a such a list as a const
static local to send to the function.
This gets rid of quite a bit of C code, and shrinks the driver by around
8k, while at the same time being more efficient.

there were several "magic" for loops, addressing gpiomux array size (4).
Adrian Busta showed that one of the loops were wrong, going from 0 to 4.
This patch provides the right fix for this trouble, by using ARRAY_SIZE

I have a Cisco VT Camera, and it was just collecting dust. I decided to
try connecting it to my Linux box at home.
Just a disgression about the product. The Cisco VT Camera is a webcam
Cisco sold to work with their IP phone hardware and software. It's mostly
useless on Windows, as it interfaces only to Cisco software. You can find
some for cheap on eBay...
Physically, it's just a Logitech Pro 4000. The only difference with the
Pro 4000 is the Cisco logo and that it's grey like the Pro 3000. I believe
Cisco is now selling the Cisco VT Camera II, which look to be something
else...
So, assuming that it was a Pro 4000 inside, I created the little patch
attached.
I'm new to webcam under Linux, but I managed to get an image from it using
xawtv, and the image looked all right, so I consider that a success. The
imaged seemed a bit small and I could not get the microphone driver loaded,
but I assume it's my lack of experience. Note that I did not try any other
type_id, but this one works great.
