[dpdk-dev] [PATCH 1/3] bus/pci: update device devargs on each rescan

[Darek Stojaczyk]

Bus rescan is done e.g. during the device hotplug,
where devargs are re-allocated. By not updating the
rte_device->devargs pointer we potentially make it
a dangling one, as previous devargs could have been
(or will be soon) freed.
