strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. Other implementations of .*get_drvinfo use strscpy so this patch brings sr_get_drvinfo() in line as well: igb/igb_ethtool.c +851 static void igb_get_drvinfo(struct net_device *netdev, igbvf/ethtool.c 167:static void igbvf_get_drvinfo(struct net_device *netdev, i40e/i40e_ethtool.c 1999:static void i40e_get_drvinfo(struct net_device *netdev, e1000/e1000_ethtool.c 529:static void e1000_get_drvinfo(struct net_device *netdev, ixgbevf/ethtool.c 211:static void ixgbevf_get_drvinfo(struct net_device *netdev, ...
