Subject: [PATCH] EDAC: Drop duplicated array of strings for memory type names
Git-commit: d6dd77ebcd22ca226171e3ff7bce7e6025ed0595
Patch-mainline: v4.17-rc1
References: bsc#1103886
Somehow we ended up with two separate arrays of strings to describe the
"enum mem_type" values.
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.
