Still, it is not clear what this test does. It would be good to add some
info about the test.

Suggestion:
If there are multiple tests available & difficult to describe in generic
way, we can add a new member "desc" to the struct funcs and print.

We are trying with different invalid combinations not garbage values.
How about "Negative test for vblank request" ?

How about s/"IOCTL events"/"Vblank & Flip events"/r ?
