Functions buffer_release() in bttv-driver.c and
vbi_buffer_release() in bttv-vbi.c are ending with:
bttv_dma_free(&fh->cap,fh->btv,buf);
For vbi it seems to be wrong. Both functions should end with:
bttv_dma_free(q,fh->btv,buf);

Before this patch, vivi were simulating a scatter gather DMA transfer.
While this is academic, showing how stuff really works on a real PCI
device, this means a non-optimized code.
There are only two memory models that vivi implements:
1) kernel alloced memory. This is also used by read() method.
On this case, a vmalloc32 buffer is allocated at kernel;
2) userspace allocated memory. This is used by most userspace apps.
video-buf will store this pointer.
a simple copy_to_user is enough to transfer data.
The third memory model scenario supported by video-buf is overlay mode.
This model is not implemented on vivi and unlikely to be implemented on
newer drivers, since now, most userspace apps do some post-processing
(like de-interlacing).
After this patch, some cleanups may be done at video-buf.c to avoid
allocating pages, when the driver doesn't need a PCI buffer. This is the
case of vivi and usb drivers.

The direct register access ioctls were defined as kernel internal only,
but they are very useful for debugging hardware from userspace and are
used as such. Officially export them.
VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h
to videodev2.h.
Types used in struct v4l2_register are changed to the userspace
exportable versions (u32 -> __u32, etc).
Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move
the check into the video_ioctl2() dispatcher so it doesn't need to be
duplicated in each driver's call-back function. CAP_SYS_ADMIN check is
added to pvrusb2 (which doesn't use video_ioctl2).

The ULi m9205 also supports isochronous transfer mode, but I have
dropped support for it because it depends on firmware and does not work
on all USB host chips. Further, I have no firmware with remote

I noticed that udev does not create a symlink for the CinergyT2 remote input
device in /dev/input/by-id, which is required if I want to have a
unique device name for lircd.
The attached patch tries to achive this. However, udev still omits the
input device for /dev/input/by-id symlinks. I think something is still
not reported correctly.
