File dmidecode-add-support-for-3-digit-versions.patch of Package dmidecode.28672

From: Jean Delvare <jdelvare@suse.de>

Subject: dmidecode: Add support for 3-digit versions
Git-commit: b6040507eb0453341af566ed20bbd591a513a542
Patch-mainline: 3.1

The version of the SMBIOS specification being implemented includes
the 3rd digit since version 3.0.0, so we should use it when comparing
with what dmidecode supports.
