I would just remove the goto from your patch.
It is safe not starting the kernel thread, but keeping the driver
initializing.
The drawback of not having the thread is not changing to stereo on some
situations and not detecting audio standard changes (some countries may
have more than one audio standard when you changing from VHF to UHF or
on Cable TV).
