There's no sense on keeping VIDEO_V4L1 Kconfig option just because of
two deprecated drivers moved to staging scheduled to die on 2.6.39.

ivtv_write_vbi_from_user()
If write() on a VBI device node fails due to a bad buffer pointer from
userspace, we should notify the application properly with EFAULT, per the
V4L2 API spec.

ivtv_write_vbi() is used for both VBI data that came from the
driver internally and VBI data that came from the user. However,
it did not use copy_from_user() for reading the VBI data from the
user buffers.
This change adds a new version of the function,
ivtv_write_vbi_from_user(), that uses copy_from_user() to read the VBI
data provided via user buffers.
This should resolve a sparse build warning reported by Dave Gilbert.

The cx18_stream struct contained a struct cx18_dvb for

saa7164_downloadfirmware()
Hi,
release_firmware() just does nothing if passed a NULL pointer. So there's
no reason to test before the call in
saa7164-fw.c::saa7164_downloadfirmware().
Removing the pointless conditional also saves a few bytes.

Support for mt9m001 (mi1300) is broken:
- Table is incomplete;
- Only one resolution is currently supported by the driver;
- Resolution is incomplete;
- it complains about broken JPEG headers.

output format as 8-bits GRAY.

Changeset 35680ba broke several devices:
- Sony Playstation Eye (1415:2000);
- Gigaware model 25-234 (0c45:628f);
- Logitech Messenger Plus (046d:08f6).
Probably more devices were broken by this change.
What happens is that several devices don't need to save some bandwidth
for audio.
Also, as pointed by Hans de Goede <hdegoede@redhat.com>, the logic
that implements the bandwidth reservation for audio is broken, since
it will reduce the alt number twice, on devices with audio.
So, let's just revert the broken logic, and think on a better solution
for usb 1.1 devices with audio that can't use the maximum packetsize.

I found that the problems people have reported with the USB-TV-stick
"Terratec Cinergy Hybrid T USB XS" (USB-ID: 0ccd:0042)
are coming from a wrong header file in the v4l-sources.
Attached is a diff, which fixes the problem (tested successfully here).
Obviously the USB-ID has been associated with a wrong chip: EM2880
instead of EM2882, which would be correct.

The RC5 old decoder used custom_irq to indicate the need of handling
the IRQ on a different way. Instead of doing it, let the core just call the
bttv input IRQ handler, and add the code there to call the legacy decoder.
While here, remove the gpioq waitqueue, as this is not used anywhere, and
add a debug msg to help removing the legacy RC5 code.

tuner
I've got code which adds support of GoTView PCI DVD3 Hybrid tuner in
cx18 module and Andy Walls in ivtv mailing-list gave me some advice on
making a patch and sending it here. So here's the patch against
staging/2.6.37-rc1 branch (the tutorial recommends to include it as
plain text but if it's the case I can surely send as an attachment):
Several comments on the patch:
1. Both users on the official Gotview forum and support said that PCI
DVD3 is very similar to Yuan MPC718 card so the main part of code is
taken from Yuan configuration. Some users reported it to work properly.
2. Everything is being initialized correctly including analog, dvb,
radio and alsa parts. Analogue part and alsa virtual card is tested by
myself using original Gotview card.
