Hi,
Can you give me an idea about what this warning means and what to do about it?
Thanks.

It means that you have an array declared like:
int x[] = {
[4] = 5, <-- designator.
6 <-- advance one step.
};
GCC handles these correctly, so I don't think we'd want to change
anything in the kernel because of them.

Hi Dan,
Thanks for the explanation. I'll just ignore these warnings.
