Yes, I checked this before I sent the initial series that this one was 
split out from.

Any additional ones introduced are from forward-declarations where the 
struct name itself tells you all the necessary information already - eg. 
"void nvif_client_dtor(struct nvif_client *);", as this is the style 
used nearly everywhere else in the driver.

A lot of the warnings you see from the code moves would fall into the 
same category.
