commit 8a3bddf67ce88b96531fb22c5a75d7f4dc41d155 upstream.
This doesn't do anything except auto-init drm_agp support when you call drm_get_pci_dev(). Which amdgpu stopped doing with

drm/amdgpu: drop deprecated drm_get_pci_dev and drm_put_dev
No idea whether this was intentional or accidental breakage, but I guess anyone who manages to boot a this modern gpu behind an agp bridge deserves a price. A price I never expect anyone to ever collect :-)
