[PATCH] fix arch/ppc64/kernel/rtc.c warnings

[Amos Waterland]

If CONFIG_PROC_FS is not asserted, the compiler emits:

 arch/ppc64/kernel/rtc.c:257: warning: `rtc_read_proc' defined but not used

Here is a patch to fix that.  It can provide a decent space savings:

   text    data     bss     dec     hex filename
 - 2956     728       0    3684     e64 arch/ppc64/kernel/rtc.o
 + 2500     664       0    3164     c5c arch/ppc64/kernel/rtc.o
