In edac_mc.c we have an exported list edac_mem_types[] that is used by a couple of drivers in debug messaged. In edac_mc_sysfs.c we have a private list that is used to display values in: /sys/devices/system/edac/mc/mc*/dimm*/dimm_mem_type /sys/devices/system/edac/mc/mc*/csrow*/mem_type this list was missing a value for MEM_LRDDR3 The string values in the two lists were different :-( Combining the lists, I kept the values so that the sysfs output will be unchanged as some scripts may depend on that.
