From 2ed055c5e32a39f5064639641f491e8a6839fe2d Mon Sep 17 00:00:00 2001 From: Thomas Monjalon Date: Wed, 26 Sep 2018 00:02:20 +0200 Subject: [PATCH] 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.
