Subject[PATCH] net: ipv4: ipconfig: fix unused variable
Date
When CONFIG_PROC_FS isn't set, variable ipconfig_dir isn't used.
net/ipv4/ipconfig.c:167:31: warning: ‘ipconfig_dir’ defined but not used [-Wunused-variable]
static struct proc_dir_entry *ipconfig_dir;
^~~~~~~~~~~~
Move the declaration of ipconfig_dir inside the CONFIG_PROC_FS ifdef to
fix the warning.

Fixes: c04d2cb2009f ("ipconfig: Write NTP server IPs to /proc/net/ipconfig/ntp_servers")
