It seems like a pretty noisy way to get a (void *) cast :/.  Maybe a  
function that has the cast but makes sure it's only used for IS_ERR()  
pointers?

/* haha, continuing the fine tradition of terrible names in this  
api..  */
static inline void *PTR_PTR(void *err_ptr) {
	BUG_ON(!IS_ERR(err_ptr) || !err_ptr);
	return err_ptr;
}

Meh.
