Subject: bus/dpaa: fix build with gcc 9.0
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=74f277101265ff3376c65270da2dcbc6d1325494;p=dpdk.git

bus/dpaa: fix build with gcc 9.0

build error:
In function ‘fman_if_init’,
    .../drivers/bus/dpaa/base/fman/fman.c:186:2:
    error: ‘strncpy’ output may be truncated copying 4095 bytes from a
           string of length 4095 [-Werror=stringop-truncation]
    strncpy(__if->node_path, dpa_node->full_name, PATH_MAX - 1);

strncpy may result a not null-terminated string,
replaced it with strlcpy
