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. Signed-off-by:

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: -

Adds a consistency check to avoid OOPS, if tuner_callback priv argument is NULL. Also, simplifies callback codes on cx88. Signed-off-by: -

Tuner refactoring broke support of tuners with LNA configurations 1 and 2 for both, analog TV and DVB-T. Additionally, this patch initializes the saa713x gpios defined by the gpiomask at driver init to avoid undefined stated at dvb. Signed-off-by:

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. Signed-off-by:

In the case of an access error to the high latency registers of the audio DSP, the interface needs to be cleared, otherwise a cascade of errors occurs. This patch is closely modeled after a proposal by Mirek Slugen Signed-off-by:

We currently do not have a method to enable instance staring if i2c adapter is NULL, in the cases of dvb demods that write to the tuner directly using calc_regs. Prevent possible wrong instance sharing for these cases until a better solution can be found. Signed-off-by:

flags used for spinlocks don't need to be initialized, except where the compiler has no way to see, that the spin_unlock_irqrestore is only called if the spin_lock_irqsave has been called before. Local variable initialization doesn't have to be protected. Signed-off-by:

As reported by Roel Kluin <12o3l@tiscali.nl>: in drivers/media/radio/radio-sf16fmr2.c:319: for (i = 0; i < ARRAY_SIZE(radio_qctrl); i++) { if ((fmr2->card_type != 11) && V4L2_CID_AUDIO_VOLUME) radio_qctrl[i].step = 65535; ... I don't understand this '&& V4L2_CID_AUDIO_VOLUME' While fixing this issue, I've revisited the volume control code and fixed CodingStyle on the changed procedures. Signed-off-by: -

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. Signed-off-by: -

I have what looks like a Geovision GV-600 (or 650) card. It has a large chip in the middle labeled CONEXANT FUSION 878A 25878-13 E345881.1 0312 TAIWAN It has an audio connector coming out from a chip labeled ATMEL 0242 AT89C2051-24PI It is identified as follows on my Debian GNU/Linux Etch (kernel 2.6.18) ... 01:0a.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 01:0a.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) ... 01:0a.0 0400: 109e:036e (rev 11) Subsystem: 008a:763c Flags: bus master, medium devsel, latency 64, IRQ 58 Memory at dfffe000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 01:0a.1 0480: 109e:0878 (rev 11) Subsystem: 008a:763c Flags: bus master, medium devsel, latency 64, IRQ 58 Memory at dffff000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 It was being detected as a GENERIC UNKNOWN CARD both by the 2.6.18 kernel and the latest v4l-dvb drivers, but it did not work at all. 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:

poll_one allocated on stack struct poll_wqueues which is pretty big structure (>500 bytes on x86_64). v4l1_compat_sync invokes poll_one in a loop, so allocate struct poll_wqueues in v4l1_compat_sync (with kmalloc) and pass it to poll_one. Signed-off-by:
