Change a 00 to just 0
Detect zero-length I2C messages and return not supported. I think I know
how to send one, but the problem is getting the slave's ack. The only
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.

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.

The code the i2c transactions was leftover from the old V4L-based ATSC
driver. It did too little with too much code. It is re-written to
remove unnecessary parameters and be more efficient. A demod register
can now be read with one function call, instead of repeating a dozen line
block of code each time.
There were msleep()'s, which appear to be unnecessary, spread around all
the I2C transactions. These have been removed. Reading SNR used to take
about 130 ms, now it's down to 1.8 ms.
Reads from the demodulator's registers do not return correct results
sometimes. Adding or removing the delays in the I2C transactions did not
appear to effect the probability of failure. If anything, the
transactions without delays were less likely to fail, but since far more
transactions could be made per second the number of failures per hour was
greater.
To increase reliability, the SNR and get_params functions will now retry
once if they get bad data back. This appears to have reduced the
probability of failure to effectively zero.
Some error messages are cleaned up or given KERN_* levels when they were
missing.
or51132_setmode() wasn't returning correct error codes, which is fixed as
well.

When trying to use a Hauppauge Nova-T Stick on a big-endian architecture
(such as powerpc) no frontend can be attached.
The attached patch fixes this problem by removing two lines in
dib0700_ctrl_rd() that try to correct the endianess on two values that
already are correct:
- /* think about swapping here */
- value = le16_to_cpu(value);
- index = le16_to_cpu(index);
With this simple patch this dvb hardware works great, thanks to anyone
involved for the good work. :)

The code of the dvb-pll driver and the lgh06xf driver is nearly
identical. The main difference is that the lgh06xf driver would set the
AGC TOP value on every tune call. The dvb-pll driver now has the ability
to set the AGC TOP when the front-end device is opened, which is a better
way to go about it. By using this ability of dvb-pll, the lgh06xf driver
is made unnecessary.
There is one other difference. dvb-pll will probe for the presence of an
I2C pll chip by doing a one byte read, the lgh06xf driver did not do
this. In some devices the PLL is not reachable over I2C at the timer the
tuner is attached. Some more initialization, such as firmware loading,
must take place first. None of the devices using a LG-H06xF should have
this problem.

Some tuners need or benefit from initialization, to change certain
settings from their power on default values.
Typically, tuners with TUA603x PLLs can benefit from setting the AGC TOP
value to something else. This patch includes code to set the AGC TOP to
103 dBuV for the Thomson DTT-761x tuners, which I have experimentally
verified gives the best SNR readings, increasing SNR by about 0.19 dB
over the default value.
Other tuners can make use of this as well. For example, the separate LG
TDVS-H06xF driver's only difference from dvb-pll is this same setting of
AGC TOP value.

A number of drivers selected DVB_PLL when they did not need it, and some
that did need it did not select it.
The DVB_PLL option is given a name and help text, so that it will show up
in the config menu. DVB_PLL support can be turned on if an out-of-tree
driver needs it.
The standard dvb fe customization support is added to dvb-pll.h. Since
all modules which select DVB_PLL do so unconditionally, it is not
possible to turn dvb-pll off when an enabled module selects it, unlike
most of the other frontend/tuner drivers. This is because the users of
dvb-pll have static references to dvb-pll symbols other than the attach
function. If these references are removed, then dvb-pll will be
disablable as the other frontend/tuner drivers are.

I did some change on the zr364xx driver following your comments:
* I replaced hardcoded values for initialization methods,
unfortunately I don't have nicer names to give for now.
* I removed the DBG() on all ioctl2 functions and used the .debug var
instead.
* Following a comment on linux-usb-devel I misunderstood, I added an
endianness test which was an error, so I removed it (the order of
the bytes in the JPEG header should not depend on endianness).
