Subject: EDAC: Add missing MEM_LRDDR4 entry in edac_mem_types[]
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b748f2de4b2f578599f46c6000683a8da755bf68;p=linux.git

EDAC: Add missing MEM_LRDDR4 entry in edac_mem_types[]

The edac_mem_types[] array misses a MEM_LRDDR4 entry, which leads to
NULL pointer dereference when accessed via sysfs or such.
