So while we are touching it, how about making it more readable:

    *
    * The standard vs the _FINISH variants differ in that the
    * standard variant will continue detecting other IOMMUs in the 
    * call list after the detection routine returns a positive number. 
    * The _FINISH variant will stop the execution chain. Both variants 
    * will still call the 'init' and ...
    *

I also fixed a 'the the' typo.

Thanks,
