Subject: bus/ifpga: fix forcing optional devargs
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=6fa4aa2b36459d6cba8c01a243a527ad12444247;p=dpdk.git

bus/ifpga: fix forcing optional devargs

Original driver requires users to input "afu_bts" args.
But driver can also work without an explicit "afu_bts" args.

Fixes: 05fa3d4a6539 ("bus/ifpga: add Intel FPGA bus library")
