Subject[PATCH] connector: hide unused procfs helpers
Date
When CONFIG_PROC_FS isn't set, gcc warning this:

drivers/connector/connector.c:242:12: warning: ‘cn_proc_show’ defined but not used [-Wunused-function]
static int cn_proc_show(struct seq_file *m, void *v)
^
fix this by adding #ifdef around it.
