From 09552b2696896dbb715be0caf91b23276f9139ba Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Thu, 7 Apr 2011 09:39:49 +0800 Subject: [PATCH] x86/mrst/vrtc: Fix boot crash in mrst_rtc_init() The sfi_mrtc_array[] only gets initialized when the sfi mrtc table is parsed, so the vrtc_paddr should be initalized after it too.
