Subject: dvb-pll: Add Samsung TDTC9251DH0 DVB-T NIM

From: Trent Piepho <xyzzy@speakeasy.org>

No datasheet, tuner data comes from code in flexcop driver.  This tuner is
also used on the AVerTV 771 supported by the bttv driver, but that code
uses a different tuner configuration, which is surprising.

Subject: dvb-pll: Add support for Samsung TBDU18132 DVB-S NIM

From: Trent Piepho <xyzzy@speakeasy.org>

Tuner parameters taken from flexcop driver.  This PLL has a 17 bit divisor
while the dvb-pll driver is designed for 15 bit divisors.  It's not a
problem as 15 bits is enough for the tuner's entire range.  But if a larger
range was wanted, it could be done by adding additional bands with the
extra divisor bits appearing as band switch bits.

From: Trent Piepho <xyzzy@speakeasy.org>

Tuner parameters determined from code in flexcop driver.  That code rounded
the divisor down instead of to the nearest value.  This was probably not
intentional and the dvb-pll version will round to nearest.

From: Antti Palosaari <crope@iki.fi>

Request demodulator auto-detect transmission parameters in case of
garbage parameters provided by application for compatibility.
That's needed at least for MPlayer compatibility currently.

Thanks to Jelle de Jong for reporting issue and providing SSH access to
Devin for debugging.

Thanks to Devin Heitmueller for hard debug work he did to find that bug.

Subject: Bug fix: stv0900 i2c repeater configuration must be set to manual.

From: Abylay Ospan <aospan@netup.ru>

In automatic mode every stop event on SDA line ends repetition.
However, in  NetUP Dual card on the same i2c bus we have several devices.
If someone using both adapters to lock simultaneously or working with CAM interface
during lock procedure, it lead to end repetition prematurely quite often.
Set stv0900 i2c repeater to manual mode prevents such situation.

Subject: zl10353 and qt1010: fix stack corruption bug

From: Jan Nikitenko <jan.nikitenko@gmail.com>

Fixes stack corruption bug present in dump_regs function of zl10353 and
qt1010 drivers: the buffer buf was one byte smaller than required -
there are 4 chars for address prefix, 16 * 3 chars for dump of 16 eeprom
bytes per line and 1 byte for zero ending the string required, i.e. 53
bytes, but only 52 were provided.

The one byte missing in stack based buffer buf can cause stack
corruption possibly leading to kernel oops, as discovered originally
with af9015 driver (af9015: fix stack corruption bug).

Subject: Use kzalloc for frontend states to have struct dvb_frontend properly

From: Matthias Schwarzott <zzam@gentoo.org>

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".
