Subject: net: secure_seq: Fix warning when CONFIG_IPV6 and CONFIG_INET are not selected
From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>
[ Upstream commit cb03db9d0e964568407fb08ea46cc2b6b7f67587 ]
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.
