Subject: bus/ifpga: remove useless driver cast
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2ed055c5e32a39f5064639641f491e8a6839fe2d;p=dpdk.git

bus/ifpga: remove useless driver cast

The rte_afu_driver is assigned to rte_afu_device.driver during probing.
There is no need of accessing the rte_afu_driver via rte_device.driver
and type casting to its container.
