foo_dev seems to be most correct term for the structure holding data
of each device instance. It is most used term in Kernel and also
examples from book Linux Device Drivers, Third Edition, uses it.

Maximum satellite symbol rate used is 45000000Sps which overflows
when multiplied by 135. As final calculation result is fraction,
we could use mult_frac macro in order to keep calculation inside
32 bit number limits and prevent overflow.
Original bug and fix was provided by Nibble Max. I decided to
implement it differently as it is now.

Same thing for si2157 as Antti did earlier for tda18212:
There is no need to print module name nor function name as those
are done by kernel logging system when dev_xxx logging is used and

After xc5000 stops working, it waits for 5 seconds, waiting
for a new usage. Only after that it goes to low power mode.
If a suspend event happens before that, a work queue will
remain active, with causes suspend to crash.

Currently, firmware retry logic keeps reading from FS every
time during the retry logic. This is not needed. Instead,
only release the firmware read after success.
While here, make the non-debug messages less verbose, as it
only matters to the user if the firmware was successfully
loaded, or if some error happened.

With the current code, if something bad happens during the
firmware init process, the device will keep trying forever,
and removing it would cause an OOPS.
Instead, try only a limited amount of time. If not, fails.

The programmed frequency on xc4000 is not the middle
frequency, but the initial frequency on the bandwidth range.
However, the DVB API works with the middle frequency.
This works fine on set_frontend, as the device calculates
the needed offset. However, at get_frequency(), the returned
value is the initial frequency. That's generally not a big
problem on most drivers, however, starting with changeset
6fe1099c7aec, the frequency drift is taken into account at
dib7000p driver.
This broke support for PCTV 340e, with uses dib7000p demod and
xc4000 tuner.
