Bjoern A. Zeeb e86707418c LinuxKPI: PCI: add counter for linux_dma_map_phys_common() errors
LinuxKPI is asking for single-segment mappings.  Some (wireless) drivers
are using this to map multi-pages and our busdma framework is not very
friendly to that as single-segments [D31823].  Add a counter so we can
track when this happens to gather more information.
