Biggest flaw of the I2C protocol: the R/W bit is the LSB instead of the

follows them, or if they are 8-bit and the R/W bit is OR-ed into the

V4L/DVB (5517): Usbvision: store the device database more efficiently
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.

V4L/DVB (5502): Sn9c102: more efficient register writing code
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.

V4L/DVB (5461): Pwc: cisco VT Camera support
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.

Instead of using a fake band with a frequency of 0 to store the sleep

V4L/DVB (5455): Dvb-pll: Adjust rounding to be consistent
Some PLLs had one half the step size added to the offset, so that the
divisor would be rounded to the nearest integer. Some didn't and so
would always be rounded down.
This makes dvb-pll round to the nearest when calculating the divisor,
without the offset needing to be fudged. PLLs that had a fudged offset
have the offset changed to be just the IF frequency.
The satellite PLL dvb_pll_philips_sd1878_tda8261 was rounding up for some
reason, and I've kept it that way.
In addition, frequencies that were rounded to the nearest kHz are
extended to full Hz resolution. One sixth MHz step sizes that were
listed as 166,666 Hz are changed to 166,667 Hz, which is slightly closer.
PLLs that were already rounding:
dvb_pll_tda665x, offset was 36 1/6 (to nearest kHz) + step/2
dvb_pll_fmd1216me, offset was 36 1/8 (to two digits) + step/2
dvb_pll_thomson_fe6600, offset was 36 1/8 (to two digits) + step/2
dvb_pll_env57h1xd5, offset was 36 1/8 + step
Note that the last PLL, dvb_pll_env57h1xd5, appears to have had a bug in
the offset. Rather than adding stepsize/2, it was adding a full
stepsize. The PLL definition originally came from the dibusb driver,
which used 36 1/8 + step/2. The change to 36 1/8 + step was probably a
mistake added when the tuner was converted to dvb-pll.

point of a zero-length message is for probing; too see if the slave will
ack its address. Since we don't know how to get the ack, we can't
support zero-length messages in a useful way, so it's probably best to
just return not supported for them.

V4L/DVB (5427): M920x: Improve I2C operations
Write some better documentation about what might be known about how the
m920x I2C works, since a datasheet is lacking.
The I2C xfer function should now handle more types of I2C transactions
than it could before. Those it can't, will return error codes instead of
being executed incorrectly. Multi-byte reads were not being done
correctly, which should be fixed.
