| |
When CONFIG_PCI_QUIRKS isn't enabled we get the warning below: drivers/pci/probe.c: In function ‘pci_bus_read_dev_vendor_id’: drivers/pci/probe.c:2221:18: warning: unused variable ‘bridge’ [-Wunused-variable] struct pci_dev *bridge = bus->self; ^~~~~~
Move the declaration of variable bridge to inside the ifdef CONFIG_PCI_QUIRKS.
