[dpdk-dev] [PATCH 2/2] eal: DPDK init doesn't fail even if device probe fails.

[Nitin Katiyar]

rte_bus_probe() doesn't return error. As a result rte_eal_init()
doesn't catch this error and thus making dpdk initialization
successful despite probe failing for devices.

This patch returns error if probe fails for any of device.
