084e24acc9 V4L/DVB (12440): Use kzalloc for frontend states to have struct dvb_frontend properly
This patch changes most frontend drivers to allocate their state structure via
kzalloc and not kmalloc. This is done to properly initialize the
embedded "struct dvb_frontend frontend" field, that they all have.

The visible effect of this struct being uninitalized is, that the member "id"
that is used to set the name of kernel thread is totally random.

Some board drivers (for example cx88-dvb) set this "id" via
videobuf_dvb_alloc_frontend but most do not.

So I at least get random id values for saa7134, flexcop and ttpci based cards.
It looks like this in dmesg:
DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S)

The related kernel thread then also gets a strange name
like "kdvb-ad-1-fe--1".

9a1b04e461 V4L/DVB (7654): tda10086: make the xtal frequency a configuration option
Some DVB-S boards, i.e. with the SD1878 tuner, use a 4 MHz reference frequency.
This reqires a different setup of the clock PLL.
This patch adds an enum to the tda10086_config struct and sets the proper
values for the boards.

This patch also fixes the DVB-S section of the MD7134_BRIDGE_2

ea75baf4b0 V4L/DVB (7186): tda10086: make the 22kHz tone for DISEQC a config option
Some cards need the diseqc signal modulated, while some just need
the envelope to control the LNB supply.

This fixes Bug 9887

c6604150ab V4L/DVB (5716): Tda10086,tda826x: fix tuning, STR/SNR values
Several people reported unreliable reception with the current driver.
Furthermore, STR and SNR values seem to be inverted.
This fix is based on a patch posted by Hartmut Hackman.
Thanks to Helmut Auer for testing and helping to optimize the patch.
tda826x:
- set baseband cut-off to 19 MHz
tda10086:
- change the parameters of the carrier recovery loop
- toggle register 0x02 between 0x35 (tuning) and 0x00 (locked)
- invert STR and SNR values
