This leads to the  \nfollowing problem when the pimary device is not VGA compatible:  \n  \n1. A PCI device with a non-VGA class is the boot display  \n2. That device is probed first and it is not a VGA device so  \n   sysfb_disable() is not called, but the device resources  \n   are freed by aperture_detach_platform_device()  \n3. Non-primary GPU has a VGA class and it ends up calling sysfb_disable()  \n4. NULL pointer dereference via sysfb_disable() since the resources  \n   have already been freed by aperture_detach_platform_device() when  \n   it was called by the other device.  \n  \nFix this by passing a device pointer to sysfb_disable() and checking  \nthe device to determine if we should execute it or not.  \n  \nv2: Fix build when CONFIG_SCREEN_INFO is not set  \nv3: Move device check into the mutex  \n    Drop primary variable in aperture_remove_conflicting_pci_devices()  \n    Drop __init on pci sysfb_pci_dev_is_enabled() \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"13 Sep 2024\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-09-13T08:45:40.000000Z"}]}
