[dpdk-dev] [PATCH v2 13/18] bus: make device recognition function public

Thu Oct 12 10:21:20 CEST 2017
As other EAL facilities now requires the bus to be explicitly mentioned,
the function rte_bus_find_by_device_name can be used by third parties to
ease the transition to a more formal device definition scheme.
