This driver is very big and complex. An error happening in the middle
of any initialization may cause the frontend to not work. So, it
needs to properly propagate error codes internally and to userspace.
Also, printing the error codes at the places it happened helps to
discover were's a bug at the code.
Before this change, a do { } while (0) loop and lots of breaks inside
were used to propagate errors. While this works, if there are
loops inside other loops, it could be easy to forget to add another
break, causing the error to not abort the function.
Also, as not all functions were reporting errors, it is hard to
discover why something failed.

On em28xx, tda18271C2 is accessible when the i2c port
is not touched. Touching on it breaks the driver.

Instead of using #ifdef I2C_LONG_ADR for some devices, convert
it into a parameter. Terratec H5 logs from the original driver
seems to need this mode.

Currently, the only parameter to be configured is the I2C
address. However, Terratec H5 logs shows that it needs a different
setting for some things, and it has its own firmware.
So, move the addr into a config structure, in order to allow adding
the required configuration bits.

The normal 16-bits read routine is called as "Read16_0". This is
due to a flags that could optionally be passed. Yet, on no places
at the code, a flag is passed there.
The same happens with 16-bits write and 32-read/write routines,
and with WriteBlock.
Also, using flags, is an exception: there's no place currently using
flags, except for an #ifdef at WriteBlock.
Rename the function as just "read16", and the one that requires flags,
as "read16_flags".
This helps to see where the flags are used, and also avoid using
CamelCase on Kernel.

This is a complex driver. Adding support for other devices with drxk
requires to be able to debug it and see where it is failing. So, add
optional printk messages to allow debugging it.

It is hard to identify the origin for those errors without a

One of the problems of the old CHECK_ERROR is that it was hiding
the status parameter. Maybe due to that, on a few places, the return
code might lead to return incorrect status:

The CHK_ERROR macro does a flow control, violating chapter 12
of the Documentation/CodingStyle. Doing flow controls inside
macros is a bad idea, as it hides what's happening. It also
hides the var "status" with is also a bad idea.
The changes were done by this small perl script:
my $blk=0;
while (<>) {
s/^\s+// if ($blk);
$f =~ s/\s+$// if ($blk && /^\(/);
$blk = 1 if (!m/\#/ && m/CHK_ERROR/);
$blk=0 if ($blk && m/\;/);
s/\n/ / if ($blk);
$f.=$_;
};
$f=~ s,\n(\t+)CHK_ERROR\((.*)\)\;([^\n]*),\n\1status = \2;\3\n\1if (status < 0)\n\1\tbreak;,g;
print $f;
And manually fixed.

Remove old DVB-T2 freq module param and detect DVB-T/T2 automatically.
Implementation is trial and error, if DVB-T does not lock try DVB-T2
and vice versa. That's done by replacing normal DVBFE_ALGO_SW with
DVBFE_ALGO_CUSTOM which gives better control for tuning process.
DVB-C still uses normal software ZigZag, DVBFE_ALGO_SW.
