There are a few cases where breaking the code into separate
lines make it worse to read. However, on several places,
breaking it to make checkpatch.pl happier is OK and improves
code readability.
So, break longer lines where that won't cause harm.

There are several places where: state->var = (some_var)
The parenthesis there are doing nothing but making it
harder to read and breaking the 80 columns soft limits.
Just get rid of it.

Thare are lots of CamelCase warnings produced by checkpatch.pl.
This weren't fixed at the time the driver got submitted due
to the lack of manpower do to such cleanup.
Now that I have one script that automates this task, cleans
it. That makes the driver almost checkpatch-compliant,
except for 80 column warnings.

Log10 routine is already defined at dvb_math.h and provides a good
enough approximation for 100 x log10(). So, instead of reinventing
the wheel, use the already existing function.
While here, don't use CamelCase on the function name.

Changeset 8f3741e accidentally broke the CNR estimation. It should
be calculated as "a + b - c". However, previously, the subtraction
by c only occurred if SNR would be positive, due to a bad binding
to DVBv3 API.
This also fixes the following warning:
drivers/media/dvb-frontends/drxk_hard.c:2556:6: warning: variable 'c' set but not used [-Wunused-but-set-variable]

The DVBv3 signal strength indicator is bogus: it doesn't range
from 0 to 65535 as it would be expected. Also, 0 means the max
signal strength.
Now that a better way to estimate it was added, use the new
way.

The AZ6007 driver released by Terratec has a better way to
estimate the signal strength, at CtrlSigStrength(). Port it
to the driver.
It should be noticed that there are two parameters there that
are tuner-specific.

The original az6007 driver has the code to calculate such
stats. Add it to the driver, reporting them via DVBv5
stats API.

Due to udev-182, the firmware load was changed to be async, as
otherwise udev would give up of loading a firmware.
Add an option to return to the previous behaviour, async firmware
loads cause failures with the tda18271 driver.

Hauppauge WinTV HVR 930C
