I think this patch is trivial and the subject itself is quite
self-explanatory and the commit message would be a copy-paste of
it.

OK, if you want I will add "some comment".

Here is where we disagree. Why lowercase is preferred over uppercase? Do
we have this in coding style (and I completely forgot about it)? Or is
it your preference (mine is too to be fair, but I also do not care
about churning the code for it)?

Thanks.

I think this is the case where the cultural habits become law, I've
been writing lower case hex values from years and my eyes are so
used to it that it looks wrong to have them written upper case.
Many maintainers reject upper case hex values.

As well as many reject the " ? : " conditional form.

In any case, you're basically right here, at this point I
don't mind if you drop it :)

Thanks,
Andi
