This example file uses the old V4L1 API. It also doesn't use libv4l.
So, it is completely obsolete. A good example already exists at
v4l-utils (v4l2grab.c):

There's no sense on keeping it on 2.6.38, as nobody is using it
anymore, at the kernel tree, and installing it at the userspace
API.
As two deprecated drivers still need it, move it to their internal
directories.

If write() on a VBI device node fails due to a bad buffer pointer from

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.

Hi,
release_firmware() just does nothing if passed a NULL pointer. So there's
no reason to test before the call in

Removing the pointless conditional also saves a few bytes.

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.
