[PATCH] new v4l2 driver: saa7134 

This patch adds a new device driver to the linux kernel.  It is for TV
cards based on the Philips SAA7134 chip.  It supports the v4l2 API and
thus depends on the v4l2 patches of the previous mails.

This is a video4linux driver for Philips SAA7130/7134 based
TV cards.
This driver is available as a module called saa7134.o ( = code
which can be inserted in and removed from the running kernel
whenever you want). If you want to compile it as a module, say M
