In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: Release the VGA arbiter client on register_device() failure
The re-order in the Fixes commit below displaced vfio_pci_vga_init() as
the last failure point of what is now vfio_pci_core_register_device()
without introducing an unwind for the VGA arbiter registration.
In current kernels this is mostly benign because vfio_pci_set_decode()
only uses pci_dev state, but the original failure path could leave a
callback with a freed vdev cookie. The stale registration also becomes
unsafe again once the callback follows drvdata to the vfio device.
Add the required VGA unwind callout.
