    edac: sb_edac.c should not require prescence of IMC_DDRIO device · de4772c6
    Luck, Tony authored
    The Sandy Bridge EDAC driver uses a register in the IMC_DDRIO CSR
    space to determine the type of DIMMs (registered or unregistered).
    But this device does not exist on some single socket Sandy Bridge
    servers.  While the type of DIMMs is nice to know, it is not essential
    for this driver's other functions. So it seems harsh to have it
    refuse to load at all when it cannot find this device.
    Make the check for this device be optional. If it isn't present
    just report the memory type as "MEM_UNKNOWN".
