Get rid of these: drivers/pci/pcie/portdrv_core.c: In function 'pcie_port_device_register': drivers/pci/pcie/portdrv_core.c:275:16: warning: 'cap_mask' may be used uninitialized in this function [-Wuninitialized] drivers/pci/pcie/portdrv_core.c:240:6: note: 'cap_mask' was declared here In some cases, 'cap_mask' may be not set in pcie_port_platform_notify, holding a garbage value.
