This commits moves the Intersil/Techwell PCI vendor ID, and
the device IDs for the TW68 PCI video capture cards.
This will allow to support future Intersil/Techwell devices

sr030pc30_get_fmt() can only succeed if both info->curr_win and
info->curr_fmt are not NULL.
If one of those vars are null, the curent code would call:
ret = sr030pc30_set_params(sd);
If the curr_win is null, it will return -EINVAL, as it would be
expected. However, if curr_fmt is NULL, the function won't
set it.
The code will then try to read from it:
mf->code = info->curr_fmt->code;
mf->colorspace = info->curr_fmt->colorspace;
with obviouly won't work.
This got reported by smatch:
drivers/media/i2c/sr030pc30.c:505 sr030pc30_get_fmt() error: we previously assumed 'info->curr_win' could be null (see line 499)

drivers/media/i2c/tc358743.c:148:19: warning: Variable length array is used.
As the maximum size is 1026, we can't use dynamic var, as it
would otherwise spend 1056 bytes of the stack at i2c_wr() function.
So, allocate a buffer with the allowed maximum size together with

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So the driver needs to export the I2C table and this
be built into the module or udev won't have the necessary information
to auto load the correct module when the device is added.

It seems that a cut-and-paste type of error occurred here:
the channel_data array size is C8SECTPFE_MAX_TSIN_CHAN, and not
C8SECTPFE_MAXCHANNEL.

2) STV0903-6110NIM (stv0903 demod + 6110 tuner, lnb24)
A NIM card is a cold plugable expansion card which usually
features a demodulator / tuner combination.

These functions are used by the core code for creating the LDVB
devices and adapter.
Addtionally some older SoC's (and potentially newer ones) have different
frontend HW which would allow those devices to be easily supported
in the future by keeping the code specific to the IP separate from the
more generic code.

This patch adds support for the c8sectpfe input HW found on
STiH407/410 SoC's.
It currently supports the TS input block, memdma engine
and hw PID filtering blocks of the C8SECTPFE subsystem.
The driver creates one LinuxDVB adapter, and a
demux/dvr/frontend set of devices for each tsin channel
which is specificed in the DT. It has been tested with
multiple tsin channels tuned, locked, and grabbing TS
simultaneously.

The B2100A dvb NIM card from ST has 2x stv0367 demodulators
and 2x TDA18212 silicon tuners, with a 16Mhz crystal. To

When using stv0367 demodulator with STi STB platforms,
we can have easily have four or more stv0367 demods running
in the system at one time.
As typically the b2120 reference design ships with a b2004a daughter
board, which can accept two dvb NIM cards, and each b2100A NIM
has 2x stv0367 demods and 2x NXPs tuner on it.
In such circumstances it is useful to print the i2c address
on error messages to know which one is failing due to I2C issues.

The Linux stack is short; we need to be able to count the number
of bytes used at stack on each function. So, we don't like to
use variable-length arrays, as complained by smatch:
drivers/media/dvb-frontends/horus3a.c:57:19: warning: Variable length array is used.
The max usecase of the driver seems to be 10 bytes + 1 for the
register.
So, let's be safe and allocate 11 bytes for the write buffer.
This should be enough to cover all cases. If not, let's print
an error message.
