In aperture_remove_conflicting_pci_devices(), match the pci device determine whether or not to call sysfb_disable(). This fixes cases where the pimary device is not VGA compatible which leads to the following problem:
1. A PCI device with a non-VGA class is the the boot display 2. That device is probed first and it is not a vga device so sysfb_disable() is not called, but the device resources are freed by aperture_detach_platform_device() 3. Non-primary GPU is vga device and it ends up calling sysfb_disable() 4. NULL pointer dereference via sysfb_disable() since the resources have already been freed by aperture_detach_platform_device() when it was called by the other device.
Fix this by calling sysfb_disable() on the device associated with it.

Thanks for investigating. I'd say we should pass the device (pdev->dev) to sysfb_disable() and do the test there. In sysfb.c, next to sysfb_disable(), you'll find sysfb_parent_dev(), which gives the Linux device of the screen_info.
The code then looks something like this:
sysfb_disable(struct device *dev) { if (dev && dev == sysfb_parent_dev(screen_info)) return
/* else do the current code */ }
there's an invocation of sysfb_disable() in drivers/of/platform.c where you can pass NULL.
