[parted-devel] [PATCH v2] Read NVMe model names from sysfs

[dann frazier]

parted currently shows the same generic model name for all NVMe devices:

  # parted /dev/nvme0n1 -s print | grep Model
  Model: NVMe Device (nvme)

If the model information is available in sysfs, display that instead:

  # parted /dev/nvme0n1 -s print | grep Model
  Model: THNSN5512GPU7 NVMe TOSHIBA 512GB (nvme)
