People tend to prefer to see non-typedef'ed type names, whenever 
possible.  In this case, it would be enough to change the type to 
unsigned long.

Lots of code throughout the kernel stores pointer values in unsigned 
long variables.  I've never heard any recommendation for using 
uintptr_t instead.
