Could we preserve alphabetical order?
I've see a lot of other tests files with this ordered by every KUNIT_CASE()
coming before KUNIT_CASE_PARAM(), with each set ordered among themselves.
Did younoticed that or are you suggesting ordering it even so? Or maybe
you're referring about another unordered thing that I didn't noticed?
Thanks,
Carlos
