#include "i915/gem_mman.h"
igt_subtest_with_dynamic("invalid-mmap-offset") {
	for_each_mmap_offset_type(t) {
		igt_dynamic_f("%s", t->name)
			test_invalid_mapping(fd, t);

In test_invalid_mapping, instead of do_ioctl(MMAP_OFFSET) use
igt_require(igt_ioctl(MMAP_OFFSET, &arg) == 0);

(Or igt_require_f if you like to keep the spiel.)
