    dmidecode: Add "Logical non-volatile device" to the memory device types
    
    When adding support for non-volative memory, we forgot to add
    "Logical non-volatile device" to the list of memory types. This
    causes NVDIMM modules to show up as <OUT OF SPEC>. Fix the problem
    by adding the missing enumerated value.

Hi, Yutzuting

Could you help me dump the bin file? I could use this bin file to debug it.

Thanks.

Hi, fuguangzhe

It's too late to fix this bug on rhel7.7, so this bug will be deferred to rhel7.8.

Thanks.

Here is a scratch build package(dmidecode-3.2-3.el7.x86_64.rpm) and i did a test as below, it can work well.

Scratch build: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=20324584

Thanks.

This is a scratch build package for rhel7.7. This package is only used for test.
Once i get all acks, it will be rebuilt for release.

I confirmed the fix has been included in RHEL7.7.

Fuguangzhe and Adrian, thank you for testing!  (See comment 10 and comment 14.)

I don't have access to a system with AEP NVDIMM hardware, but I was able to test and verify with the attached AEP.dmi dump file.
