4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit b748f2de4b2f578599f46c6000683a8da755bf68 upstream.
The edac_mem_types[] array misses a MEM_LRDDR4 entry, which leads to
NULL pointer dereference when accessed via sysfs or such.
