[Impact]
  
  Some Dell systems crash when disabling Nvidia dGPU with I+N configurations
  because Nvidia's driver does not supports RTD3.

[Fix]

  BIOS added solutions with _OSI string "Linux-Dell-Video" to workaround RTD3, 
  and a patch to report _OSI("Linux-Dell-Video") is required in Linux kernel.

  The patches are included in upstream and are cherry-picked from Linus's repo.

[Regression potential]

  No regression as all but targeted firmware will not use this _OSI string
