resources: skip sanity check of busy resources
Impact: reduce false positives in iomem_map_sanity_check() Some drivers (vesafb) only map/reserve a portion of a resource. If then some other driver comes in and maps the whole resource, the current code WARN_ON's. This is not the intent of the checks in iomem_map_sanity_check(); rather these checks want to warn when crossing *hardware* resources only. This patch skips BUSY resources as suggested by Linus. Note: having two drivers talk to the same hardware at the same time is obviously not optimal behavior, but that's a separate story.
