A more detailed commit body:

This patch fixes the build failure with message:
    drivers/net/mlx5/mlx5_ethdev.c: In function ‘mlx5_sysfs_switch_info’:
    drivers/net/mlx5/mlx5_ethdev.c:1381:3: error: ignoring return value
    of ‘fscanf’, declared with attribute warn_unused_result [-Werror=unused-result]
    fscanf(file, "%s", port_name);
    ^
Which reproduces on Ubuntu 16.04 LTS with
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.10) 5.4.0 20160609.

Fixes: b2f3a3810125 ("net/mlx5: support new representor naming format")
