If anyone has any objections, please let me know. ------------------ From: Wentao Liang commit 67b4411538c8341692548429d43256f25be99f7a upstream. pci_get_domain_bus_and_slot() takes a reference to the PCI device, which is never released once the memory size has been read from its config space. Drop the reference before returning.
