Hi,

Here are two ways to accomplish the compilation problem,
the second one might be the easier one for you.

One commonly working way to fix odd compilation problems:
1. Check out from linuxtv.org v4l-dvb-linuxtv (the main branch).
2. Check from there the file v4l-dvb-linuxtv/linux/drivers/media/???/s400.c

There you will probably find the fix for the s400.c problem.
Then you just copy that fix into multiproto s400.c version and compile 
the multiproto version again.

So the wisdom is, that usually v4l-dvb-linuxtv will gain all 
compatibility fixes for many kernels.

Another way to fix compilation problem is to try to disable s400.c 
altogether:
Add into v4l/versions.txt s400.c driver's definition under [2.6.99] and 
remove it from other places in versions.txt.

Idea is that you inform compilation system that s400 doesn't work yet in 
your kernel, but instead it will work under 2.6.99.
Kernel compilation system desides to skip the compilation of the broken 
driver and because you don't need
s400.c, it doesn't matter for you.

Happy hunting.

Regards,
Marko Ristola
