Subject: bus/fpga: use strlcpy instead of strncpy
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4c80789430d617d7ed3159d80041919fdddb6cd7;p=dpdk.git

bus/fpga: use strlcpy instead of strncpy

Gcc 8 reports a build error:

drivers/bus/ifpga/ifpga_bus.c:161:2: error: ‘strncpy’ specified
bound 256 equals destination size [-Werror=stringop-truncation]
  strncpy(afu_pr_conf.bs_path, path, sizeof(afu_pr_conf.bs_path));
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
