From f383d00a0d1f94a7d60c753ec8e3e402889f9622 Mon Sep 17 00:00:00 2001 From: Daniel Kiper Date: Mon, 30 Jun 2014 19:53:04 +0200 Subject: [PATCH] arch/x86: Remove efi_set_rtc_mmss() efi_set_rtc_mmss() is never used to set RTC due to bugs found on many EFI platforms. It is set directly by mach_set_rtc_mmss(). Hence, remove unused efi_set_rtc_mmss() function.
