https://code.launchpad.net/~alexhung/plainbox-provider-checkbox/+git/plainbox-provider-checkbox/+merge/392196

ACPI OEM _OSI strings are used as workaround for NV cards in 2017, and they shouldn't be present in new BIOS code. If they do, it is likely they are used as dirty workarounds.

OEM _OSI strings were for workarounds in 2016 and 2017. They shouldn't be
used in BIOS/firmware anymore.
