A couple of nitpicks: all these should be either do_ioctl() for
success, or do_ioctl_err() for failure, which not only cuts down the
number of lines a bit, but also shows you the exact condition which
occurred (e.g. it'll show that errno was -EBUSY rather than expected
-EINVAL without having to round-trip through the reporter). Similarly,
all your igt_assert(x == y) should be igt_assert_eq(x, y), or any of
the igt_assert_{eq,neq} variants, e.g. _u32 for comparing uint32_t.
You can also use do_or_die(foo) as shorthand for igt_assert_eq(foo,
0).
