2008-04-24V4L/DVB (7402): add macro validation for v4l_compat_ioctl32Douglas Schilling Landgraf

2008-04-24V4L/DVB (7401): radio-si470x: unplugging fixedTobias Lorenz
This patch fixes several kernel oops, when unplugging device while it is in use: Basically the patch delays freeing of the internal variables in si470x_usb_driver_disconnect, until the the last user closed the device in si470x_fops_release. This was implemented a while ago with the help of Oliver Neukum. I tested the patch five times (unplugging while in use) without oops coming from the radio-si470x driver anymore. A remaining oops was coming from the usbaudio driver, but this is someone else task. Hopefully this fixed all unplugging issues.

2008-04-24V4L/DVB (7399): Removes video_dev from tuner-xc2028 config structMauro Carvalho Chehab
The video_dev parameter, on tuner-xc2028 were used to pass i2c private data to tuner_callback. Since the driver already have a pointer to i2c_adap->algo_data, uses this instead. This parameter were used also as a magic number to idenfity if two drivers are trying to register the same xc3028 tuner. This occurs with boards with DVB support, where both DVB and V4L drivers will share the same tuner. Instead of using the algo_data as a private number, after this patch, the driver will use i2c_adap->dev, with seems more consistent. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7398): Adds an error if priv argument of tuner_callback is NULLMauro Carvalho Chehab

2008-04-24V4L/DVB (7392): saa7134: support 2nd DVB-S section of the MD8800Hartmut Hackmann
There are some restrictions: - The 2nd DVB-S section will only work if the 1st is configured for DVB-S too. so "options saa7134-dvb use_frontend=0,1" won't work. - Currently it is not possible to set the higher LNB supply voltages, so 14V instead of 13V in the 2nd section. - It is not possibe to turn off the 2nd LNB supply independently. This comes from the problem that the 2nd section can't access the i2c interface of the LNB supply chip.

tuner-xc2028 needs to know when a DVB module is sharing the same analog tuner. This is done by comparing a magic number that needs to be the same on analog and on digital. To make easier, this magic number is a pointer to some data struct. With the previous code, two different pointers were using, causing a miss-detection.

The card has sixteen (16) BNC video inputs, four of them on the board itself and twelve on three daughter-cards. It has a single bt878 chip, no tuner and what looks like and audio input. After doing some research I managed to get only eight channels working by forcing card=125 and those DID NOT match channels 0-7 on the card, and no audio. Based on what was working for card=125, I added the card definition block, added a specific muxsel routine and got the card working fully with xawtv, where the sixteen channels show up as Composite0 to Composite15, matching the channel labels in the card and daughter-cards. I have made no efforts yet to get audio working, but would appreciate any pointers. Signed-off-by: Ernesto Hernández-Novich <emhn@usb.ve> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
