dmidecode/dmioem-fix-segmentation-fault-in-dmi_hp_240_attr.patch
Jean Delvare f678f58aac 2 recommended fixes from upstream:
- news-fix-typo.patch: We ship the NEWS file so avoid including a
  typo in it.
- dmioem-fix-segmentation-fault-in-dmi_hp_240_attr.patch: Passing
  NULL to a %s printf conversion specifier is illegal, and can
  result in a segmentation fault. Current version of glibc doesn't
  mind, but alternative, past or future libc implementations could
  crash, so let's fix it.

Subject: dmioem: Fix segmentation fault in dmi_hp_240_attr()
Patch-mainline: yes
Git-commit: c3357b532941a8df387618e692e522cc7a43b3e8
pr_attr() does not accept a NULL format string. glibc can deal with
it, but FreeBSD's libc chokes on it.
Display the attributes as a list instead. Pack the attribute name and
status into a single formatted string that can be passed to
pr_list_item(). That's arguably a hack, but it's cheap, non-intrusive,
and works nicely in the end.
Bug reported by Scott Benesh (Microchip).
