ipv4: ipconfig: avoid unused ic_proto_used symbol
When CONFIG_PROC_FS, CONFIG_IP_PNP_BOOTP, CONFIG_IP_PNP_DHCP and CONFIG_IP_PNP_RARP are all disabled, we get a warning about the ic_proto_used variable being unused: net/ipv4/ipconfig.c:146:12: error: 'ic_proto_used' defined but not used [-Werror=unused-variable] This avoids the warning, by making the definition conditional on whether a dynamic IP configuration protocol is configured. If not, we know that the value is always zero, so we can optimize away the variable and all code that depends on it. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.
