Summary

In the Linux kernel, the following vulnerability has been resolved:

EDAC/i10nm: fix refcount leak in pci_get_dev_wrapper()

As the comment of pci_get_domain_bus_and_slot() says, it returns a PCI device with refcount incremented, so it doesn't need to call an extra pci_dev_get() in pci_get_dev_wrapper(), and the PCI device needs to be put in the error path.
