I have to patch my kernel(2.6) for my webcam

here's the only documentation for drivers

-**********************************************-
Patch for kernel 2.6 and a Makefile for 2.6. And some small bugg fixes.
So to compile with a 2.6 kernel :

cvs -dserver:anonymous@cvs.nw802.sourceforge.net:/cvsroot/nw802 login
cvs -z3 -dserver:anonymous@cvs.nw802.sourceforge.net:/cvsroot/nw802
co nw802-2.4
cd nw802-2.4
cp Makefile.26 Makefile
patch -p0 < patch-2.6
make clean
make
-**********************************************-

can you pls explain that
how can I patch the kernel?

This is not a kernel patch but a patch for module code which seem required here to
run under 2.6 kernel

Follow the instructions and after make, maybe a make install as root will install your
module.
