Sorry I totally didn't realize that. Generally we don't have a lot of igt
testcase for libdrm really, imo it's usually simpler to just add the
interface to each part. Since this is such a simple one there's no need to
have a low-level test and the libdrm test on top, but that's what I'd do
if there's something worth testing in libdrm. Because for complex
functionality I really want to get the bare-metal tests in together with
the kernel part. Stalling for libdrm release could take longer.

And yes, personally I'd just have open-coded the getparam call here in
igt, but that's just a bikeshed.
