[PATCH 2.6.17.7] Fix budget-av compile failure

From: Andrew de Quincey <adq_dvb@lidskialf.net>

Currently I am doing lots of refactoring work in the dvb tree. This bugfix
became necessary to fix 2.6.17 whilst I was in the middle of this work. 
Unfortunately after I tested the original code for the patch, I generated 
the diff against the wrong tree (I accidentally used a tree with part of 
the refactoring code in it). This resulted in the reported compile errors 
because that tree (a) was incomplete, and (b) used features which are 
simply not in the mainline kernel yet.

Many apologies for the error and problems this has caused. :(
