I will change it as follows:

static inline void*
test_ring_inc_ptr(void *obj, int esize, unsigned int n)
{
        int sz;

        sz = esize;
        /* Legacy queue APIs? */
        if ((esize) == -1)
                sz = sizeof(void *);

        return (void *)((uint32_t *)obj + (n * sz / sizeof(uint32_t)));
}
