Some tests, such as overflow_kunit(), uses unsigned int,
But kunit_binary_assert_format() only prints signed int,
this commit also deals with the unsigned int print.

I agree that you found a bug here; however, I disagree that this is
the correct fix. Given that the value is stored as a long long; isn't
the value always stored as a signed value? So if the value overflows,
won't it still not pass the check you have here?

Oops, Thanks!
I'll fix it.

Hi Brendan,
Actually https://patchwork.kernel.org/patch/11724995/
solves my problem with unsigned int, since I can customize
the Expected message with this patch.
I think you can ignore this patch :)
