Subject: bus/pci: remove unnecessary cast
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=40094b8eea31013f8df285a4ebdd7cc5e0d8e6cd;p=dpdk.git

bus/pci: remove unnecessary cast

The variables 'vfio_res->nb_maps' and 'i' are of type int. The type
casting of 'vfio_res->nb_maps' is redundant and not required.
