I did look at this too and could only find a mixture of ways people have
done this. Isn't the correct type for this intptr_t?
That's true. There are lot of variations of how it's done. I had
referred one of the gpio driver for this. I think it's safe to use
unsigned long instead as Stephen suggested.
Btw I don't see intptr_t defined in include/linux/types.h.

then this could just be a cast to unsigned long?
