Subject[PATCH 1/4] ACPI: OSI: Remove Linux-Dell-Video _OSI string
Date
This string was introduced because drivers for NVIDIA hardware
had bugs supporting RTD3 in the past. Thoes bugs have been fixed
by commit 5775b843a619 ("PCI: Restore config space on runtime resume
despite being unbound"). so vendors shouldn't be using this string
to modify ASL anymore.
