[linux-dvb] Problem making v4l driver tree

Mike,
          I usually find that it failing to find the include files 
indicates that the kernel source/headers are not installed correctly. I 
find that for my distro doing a make kernel-links with perhaps a depmod 
thrown in fixes this kind of problem. I don't know about the IRQ loop 
but then honestly I don't know much about this stuff.

Cheers Paul
