The lock_norm module parameter doesn't look terribly useful. If you
don't want to change the norm, just don't change it. As a matter of
fact, no other v4l driver has such a parameter.

The code to optimize the usercopy only checked the ioctl NR field. However,
this code is also called for non-V4L2 ioctls (either private or ioctls from
linux/dvb/audio.h and linux/dvb/video.h for decoder drivers like ivtv).
If such an ioctl has the same NR as a V4L2 ioctl, then disaster strikes.
Modified the code to check on the full command ID.
Thanks to Martin Dauskardt for tracing the ivtv breakage to this particular
change.

V4L/DVB (10827): Add support for GeoVision GV-800(S)
I have a GeoVision GV-800(S) card, it has 4 CONEXANT BT878A chips.
It has 16 video inputs and 4 audio inputs, and it is almost identical
to the GV-800, as seen on http://bttv-gallery.de .
The only difference appears to be the analog mux, it has a CD22M3494

picture: http://www.gsbr.com.br/imagem/kits/GeoVision%20GV%20800.jpg .
This card wasn't originally supported, and it was detected as
UNKNOWN/GENERIC. The video inputs weren't working, so I tried
"forcing" a few cards like the GeoVision GV-600, but there was still
no video. So I made a patch to support this card, based on the Kodicom
4400r.

As you can see, the GV-800(S) card is almost identical to the GV-800
on bttv-gallery, so this patch might also work for that card. If not,
only a few changes should be required on the gv800s_write() function.
After this patch, the video inputs work correctly on linux 2.6.24 and
2.6.27 using the software 'motion'. The input order may seem a little
odd, but it's the order the original software/driver uses, and I decided
to keep that order to get the most out of the card.
I tried to get the audio working with the snd-bt87x module, but I only
get noise from every audio input, even after selecting a different mux
with alsamixer. Also, after trying to play sound from those sources, I
randomly get a RISC error about an invalid RISC opcode, and then that
output stops working. I also can't change the sampling rate when
recording. Any pointers to adding audio support are welcome.

V4L/DVB (10811): videodev: only copy needed part of RW ioctl's parameter
There are many RW ioctls() in v4l2 where userspace only supplies one or two
of the first fields in the structure passed to the ioctl. The driver then
fills in the rest of the fields.
Instead of copying the entire structure from userspace to the kernel we
only need to copy those fields that userspace is actually supposed to
supply.
What's more, the fields that are meant to be only be output from the driver
can be zeroed out in the videodev code, in case the driver doesn't fill
them all in. Many of the ioctl handlers in v4l2_ioctl do this already, but
my patch does this at one common point and so all the memsets for each
ioctl can be deleted.
For VIDIOC_G_SLICED_VBI_CAP, which has one input field ('type') and other
output-only fields, the input field is near the end of the structure
instead of at the beginning. So there is still a memset in it's ioctl
handler to zero out the beginning of the struct.
There were a couple mistakes with the existing code:
For VIDIOC_G_AUDIO the index field was preserved, but G_AUDIO is a read
only ioctl so nothing is copied from userspace to preserve.
For VIDIOC_G_FREQUENCY the tuner field was not preserved like it should
have been. This would be a problem if there was any hardware with more
than one tuner/modulator.
For VIDIOC_ENUM_FRAMESIZES and VIDIOC_ENUM_FRAMEINTERVALS, none of the
fields were preserved even though each ioctl has several field that are
supposed to be inputs to the driver! Obviously these ioctls don't get
used much. The index field is needed if the driver has multiple
discrete sizes/rates and other fields can be used too, e.g. if the size
depends on pixel format or frame rate depends on image size for
example.
