Use strlcpy where possible to ensure the string is \0 terminated. Use always sizeof(string) instead of 32, ETHTOOL_BUSINFO_LEN and custom defines. Use snprintf instead of sprint. Remove unnecessary inits of ->fw_version Remove unnecessary inits of drvinfo struct. Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>
