Logitech ViewPort AV 100 has the same internals as Cisco VT Camera.
Fixing Pwc driver to handle it properly.
Also, fixed the comments for both cameras.
Thanks to Martin Rubli for pointing me this.

I have a Cisco VT Camera, and it was just collecting dust. I decided to
try connecting it to my Linux box at home.
Just a disgression about the product. The Cisco VT Camera is a webcam
Cisco sold to work with their IP phone hardware and software. It's mostly
useless on Windows, as it interfaces only to Cisco software. You can find
some for cheap on eBay...
Physically, it's just a Logitech Pro 4000. The only difference with the
Pro 4000 is the Cisco logo and that it's grey like the Pro 3000. I believe
Cisco is now selling the Cisco VT Camera II, which look to be something
else...
So, assuming that it was a Pro 4000 inside, I created the little patch
attached.
I'm new to webcam under Linux, but I managed to get an image from it using
xawtv, and the image looked all right, so I consider that a success. The
imaged seemed a bit small and I could not get the microphone driver loaded,
but I assume it's my lack of experience. Note that I did not try any other
type_id, but this one works great.

The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly. To work around
this, makefiles would define some new macro based on the setting of a
config variable. e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary. This patch gets ride of these extra defines and
just uses the CONFIG_* settings directly.

Main changes:
- There were several checks for usb release routines that were removed, since
the routine itself checks for null values:
usb_free_urb, usb_kill_urb, usb_unlink_urb
Should be checked if this really happens on older kernels.
- updated sound/oss/btaudio.c
- replaced SLAB_ATOMIC to GFP_ATOMIC

Kernel-sync:
This patch is required to allow compilation of the tree with kernel
2.6.19.
This is the original description of the original patch, signed by
David Howells <dhowells@redhat.com>:
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

Apply the relevant parts of a patch from Pete Zaitcev <zaitcev@redhat.com>
kernel-sync:
Original description:
The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".
The usbmon splits such cases already thanks to its timestamp, but
it's not always available.
I adjusted all drivers which I found affected (by searching for "urb").
Out of tree drivers may suffer a little bit, but I do not expect much
breakage. At worst they may print a few messages.

Remove code that tries to handle backward compatibility for
v4l_printk_ioctl(), but ironically has the opposite effect. For kernels
< 2.6.16, a local version of v4l_printk_ioctl(), which doesn't even
compile, is removed. For kernels >= 2.6.16, the unnecessary extern
prototype is removed, as the function is prototyped in
media/v4l2-common.h.

The videodev.h and videodev2.h describe the public API for V4L and V4L2.
It shouldn't have there any kernel-specific stuff. Those were moved to
v4l2-dev.h.
This patch removes some uneeded headers and include v4l2-common.h on all
V4L driver. This header includes device implementation of V4L2 API provided
on v4l2-dev.h as well as V4L2 internal ioctls that provides connections
between master driver and its i2c devices.
