V4L/DVB (4922): Add usbvision driver
This patch adds usbvision into V4L/DVB HG tree. Usbvision driver is a GPL driver, made by: Joerg Heckenbach <joerg@heckenbach-aw.de> and Dwaine Garden <DwaineGarden@rogers.com> V4L2 migration made by: Thierry Merle <thierry.merle@free.fr> Kconfig/Makefile scripts by: Mauro Carvalho Chehab <mchehab@infradead.org> Signed-off-by: Joerg Heckenbach <joerg@heckenbach-aw.de> Signed-off-by: Dwaine Garden <dwainegarden@rogers.com> Signed-off-by: Thierry Merle <thierry.merle@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

There are more than 50 different USB video devices based on
|

NT1003/1004/1005 USB Bridges. This driver enables using those
|

devices.
|

To compile this driver as a module, choose M here: the

module will be called ovcamchip.
