Subject: [PATCH 7/7] RAS, extlog: Adjust init flow
Date: Thu, 15 May 2014 04:30:46 -0400	[thread overview]
Message-ID: <1400142646-10127-8-git-send-email-gong.chen@linux.intel.com> (raw)
In-Reply-To: <1400142646-10127-1-git-send-email-gong.chen@linux.intel.com>

Unless the platform has eMCA related capability, don't
need to check if there is conflict with EDAC driver.
