In the Linux kernel, the following vulnerability has been resolved: PCI: dwc: Avoid dwc_pcie_rasdes_debugfs_deinit() NULL dereference when no RAS DES capability dwc_pcie_rasdes_debugfs_init() returns success when the controller has no RAS DES capability, leaving pci->debugfs->rasdes_info unset. The common debugfs teardown path still calls dwc_pcie_rasdes_debugfs_deinit(), which dereferences rasdes_info unconditionally. Return early when no RAS DES state was allocated. In that case no RAS DES mutex was initialized, so there is nothing to destroy. [mani: reworded subject]
