I didn't mean that another procesess may interrupt execution, no. I meant
that handle_syncstart itself may return before SYNC_START stage. There is
the following code in handle_syncstart:
if((err = prepare_output(adev, adev->dmap_out)) < 0)
return err;
If prepare_output fails handle_syncstart will return before SYNC_TRIGGER
stage, that's what I meant saying "interrupted". Maybe I didn't express this
clearly.
