I was going to wait until tonight (12 hours away) when I could beat on 
the changes thoroughly.  However the other pvrusb2 bits are low risk, so 
I'm testing it right now before heading to work and will post the pull 
request shortly afterwards.

Hmm, audio isn't working.  I just also tried a 29xxx (with 
saa7115+msp3400) and audio is OK there, so there's still something else 
apparently broken involving the pvrusb2 driver and cx25840.  However 
this whole thing still is an improvement over what's there now so I'm 
posting the pull request anyway.  I will do more digging on the audio 
problem tonight.
