Thanks a lot. With this patch applied I am able to compile the DVB driver
even with kernel 2.6.5 :-)
Please check it into the CVS, so that a freshly fetched CVS driver version
will compile fine.

I even managed to compile the driver on a machine that is actually running
kernel 2.4.20, because that's a much faster machine, which I will not (yet)
update to kernel 2.6. I'll post a separate message on the driver ML with
a summary of what it takes to "cross compile" the driver.

However, the latest greatest dvb-kernel driver still has the dropout problem
every few seconds, so I guess I'll need to find out what I did in the old
DVB driver to fix (or at least work around) this, and see whether somebody
has removed that fix/workaround in dvb-kernel...
