This patch cleans up the source code of the b2c2 flexcop-driver. It is the first of a total of two.

The code is now passing the checkpatch-script.

When resetting the PID-filter block a safety msleep(1) was injected. Now that the function is called from interrupt context, it was replaced with a udelay. It seems that this delay is not necessary at all, let's remove it for now and test a while.

If the card is ejected on some systems you get a spew of messages as other

disable.

We don't need to spew them all out

Separate tuning table for DVB-C solves tuning problem at 388MHz

TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that
existing frequency table is valid for DVB-T.

This is suggested by the name of the table: tda827xa_dvbt.

Added a table for DVB-C with the name tda827xa_dvbc.

Added runtime selection of the DVB-C table when the tuner is type
FE_QAM.

This should leave the behaviour of this driver with with DVB_T tuners
unchanged. This modification is in file tda827x.c

The tda827x.c gives the following warning message when debug=1:

tda827x: tda827x_config not defined, cannot set LNA gain!

Solved this by adding a tda827x_config struct in budget-ci.c.

There are several Kconfig items using CUSTOMIZE. Yet, most use the English
writing CUSTOMISE. This generates lots of trouble, because people sometimes type
the Kbuild item different.

Let's standardise every occurrence using the same syntax.

The changes were generated by this small shell script:

for i in `find linux -type f`; do sed s,CUSTOMIZE,CUSTOMISE,g $i >/tmp/a && mv /tmp/a $i; done

As reported by Randy Dunlap <randy.dunlap@oracle.com>:
ERROR: "dvb_dummy_fe_ofdm_attach" [drivers/media/video/cx231xx/cx231xx-dvb.ko] undefined!

This happens since cx231xx DVB part still misses the frontend modules.
So, the dummy frontend were used for development. The proper fix is to
implement the DVB modules there, as they will be required.

While this won't happen, lets allow the compilation with or without the
dummy FE testing module.
