[media] tuner-i2c: be consistent with I2C declaration

2015-06-23T13:01:45+00:00

On alpha, gcc warns a log about signed/unsigned ballance, with
produces 3185 warnings. Ok, this is bogus, but it indicates that
the declaration at V4L2 side is not consistent with the one at
I2C.

With this trivial patch, the number of errors reduce to 2959
warnings. Still too much, but it is 7.1% less. So let's do it.

[media] e4000: Fix rangehigh value

2015-05-20T16:53:33+00:00

As reported by smatch:

drivers/media/tuners/e4000.c:287:32: warning: constant 2208000000 is so big it is long long
drivers/media/tuners/e4000.c:287:32: warning: decimal constant 2208000000 is between LONG_MAX and ULONG_MAX. For C99 that means long long, C90 compilers are very likely to produce unsigned long (and a warning) here

[media] e4000: various small changes

2015-05-20T16:48:31+00:00

* Rename device state from 's' to 'dev'.
* Move single include to driver private header.
* Change error handling type of each function to one I tend use
nowadays.
* Remove dummy register write from init. Even Windows driver does this
multiple times remove it as I have never seen any I2C errors.
* Define I2C client pointer for each function and use it.
* Do not clean tuner ops during driver remove - not needed.
* Disable sysfs device bind / unbind. We are not allowed manually
bind / unbind device from the driver currently.
* Rename some other variables.

[media] e4000: revise synthesizer calculation

2015-05-20T16:46:13+00:00

Update synthesizer calculation to model I prefer nowadays. It is
mostly just renaming some variables to ones I think are most standard.
Also add 'schematic' of synthesizer following my current understanding.

[media] fc2580: implement V4L2 subdevice for SDR control

2015-05-18T18:58:10+00:00

Implement V4L2 subdevice for bandwidth and frequency controls of
SDR usage. That driver now implements both DVB frontend and V4L2
subdevice. Driver itself is I2C driver. Lets see how it works.
