    Subject[PATCH 03/10] atmel: hide unused procfs helpers
    Date
    When CONFIG_PROC_FS isn't set, gcc warning this:

    drivers/net/wireless/atmel/atmel.c:1402:12: warning: ‘atmel_proc_show’ defined but not used [-Wunused-function]
    static int atmel_proc_show(struct seq_file *m, void *v)
    ^
    fix this by adding #ifdef around it.
