net: secure_seq: Fix warning when CONFIG_IPV6 and CONFIG_INET are not selected
net_secret() is only used when CONFIG_IPV6 or CONFIG_INET are selected. Building a defconfig with both of these symbols unselected (Using the ARM at91sam9rl_defconfig, for example) leads to the following build warning: $ make at91sam9rl_defconfig # # configuration written to .config # $ make net/core/secure_seq.o scripts/kconfig/conf --silentoldconfig Kconfig CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h make[1]: `include/generated/mach-types.h' is up to date. CALL scripts/checksyscalls.sh CC net/core/secure_seq.o net/core/secure_seq.c:17:13: warning: 'net_secret_init' defined but not used [-Wunused-function] Fix this warning by protecting the definition of net_secret() with these symbols.
