Removing of unnecessary spinlock
Based on the discussion on linux-dvb it seems that ISR:s are already
serialized by the linux kernel and thus drivers won't have to specify
their own facilities for ISR serialization.
There is a good summary of concurrency and ISRs on page 268 Linux Device

Thanks for the debugging!
Cheers,
Tim.
