------------------------------------------------------
Subject: drivers/edac: add edac_mc_find API
From: Douglas Thompson <dougthompson@xxxxxxxxxxxx>
This simple patch adds an important CORE API for EDAC that EDAC drivers can
use to find their edac_mc control structure by passing a mem_ctl_info
'instance' value
Needed for subsequent patches
