| 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).
