Hi,

Correct, but I didn't want to mix several things in the same commit.
This one is dedicated to automatically generated changes done with 
coccinelle.

I plan to have another set of such clean-ups once "wrappers in 
include/linux/pci-dma-compat.h are gone"

However, if it is prefered to have only one patch, I can resubmit.
