Please, don't use the get_maintainers script. This CCs too many people, really. 
As for pxa168, only CC linux-arm-kernel, Eric, Haojian and that's about it 
(fixed). Thanks

I can't comment on the code, though Haojian, is there any particular reason why 
the call's twice in there? Maybe some HW quirk or something?

Cheers
