See patch below. -Robert -- >8 -- From: Robert Richter Subject: [PATCH] efi: Unify dmi setup code over architectures arm/arm64, io64 and x86 All architectures (arm/arm64, io64 and x86) do the same here, so unify the code. Note: We do not need to call dump_stack_set_arch_desc() in case of !dmi_available. Both strings, dmi_ids_string and dump_stack_arch_ desc_str are initialized zero and thus nothing would change.
