In the Linux kernel, the following vulnerability has been resolved:
thermal: intel: int340x: processor: Fix warning during module unload
The processor_thermal driver uses pcim_device_enable() to enable a PCI
device, which means the device will be automatically disabled on driver
detach. Thus there is no need to call pci_disable_device() again on it.
With recent PCI device resource management improvements, e.g. commit
f748a07a0b64 ("PCI: Remove legacy pcim_release()"), this problem is
exposed and triggers the warining below.
