From: Feilong Lin <linfeilong@xxxxxxxxxx> In enable_slot() in drivers/pci/hotplug/acpiphp_glue.c, if pci_get_slot() will return NULL, we will do not set SLOT_ENABLED flag of slot. if one device is found by calling pci_get_slot(), its reference count will be increased. In this case, we did not call pci_dev_put() to decrement the its reference count, the memory of the device (struct pci_dev type) will leak. Fix it by calling pci_dev_put() to decrement its reference count after that pci_get_slot() returns a PCI device.
