kcalloc()?

It's normally better to avoid splitting errors message so people can
grep if they see the error.

That's going to complain fairly loudly for all existing DTs isn't it and
it's kind of redundant if all the cores have the same capacity (which is
a very common case)?  How about printing an error only if we already
found one, or printing a single warning at the end if we didn't get
anything?
