Yikes!

The patch description explains the blunder... Sorry about this.

We've got a fix, but would you mind testing it, Edgar, before I request
that this gets added to the stable queue?

Thanks for reporting,

[2.6.17.7 PATCH] Fix budget-av compile failure

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. :(
