2009-11-07V4L/DVB (13079): dib0700: fixed xc2028 firmware loading kernel oopsMartin Samek
Fixing kernel oops when driver attemps to load xc2028 firmware. Note by djh: the patch contribute by Martin is a port of a fix I made during the PCTV 340e development. It's a temporary workaround that fixes a regression (an OOPS condition) and the real fix should be in the code that manages the i2c master on the dib7000p. But this fix does address the immmediate regression and should be merged upstream until we do a cleaner fix.

2009-09-12V4L/DVB (12481): Fix lowband tuning with tda8261Julian Scheel
Attached is a patch which fixes tuning to low frequency channels with stb0899+tda8261 cards like the KNC TV-Station DVB-S2. The cause of the issue was a broken if construct, which should have been an if/else if, so that the setting for the lowest matching frequency is applied. Without this patch for example tuning to "arte" on Astra 19.2, 10744MHz SR22000 failed most times and when it failed the communication between driver and tda8261 was completely broken. This problem disappears with the attached patch. Signed-off-by: Julian Scheel <julian@jusst.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

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.

2009-08-13V4L/DVB (12440): Use kzalloc for frontend states to have struct dvb_frontend ↵Matthias Schwarzott
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".

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 patch swaps the tables in use. It also fixes a possible one in a million condition where state->dev_ver implies an older Cut (Cut < 2.0, eventhough the driver doesn't attach to any Cut older than 2.0) or even negative (due to a bad I2C bus master driver) for the card combination.
