Hello Shelley Chen, Hung-Te Lin, build bot (Jenkins), Yu-Ping Wu,

device/pci_device.c: Scan only one device for PCIe

Only scan one device if it's a PCIe downstream port.

A PCIe downstream port normally leads to a link with only device 0 on
it. As an optimization, scan only for device 0 in that case.
