Some gcc versions complain about sata_via, others complain about
something else.  Some versions complain about some iterator usages while
not complaining about others, but none of those complaints is actually
wrong or dangerous.  I don't think adding = NULL whenever some version
of gcc complains is the right approach.

Thanks.
