// /sys/devices has a directory structure which reflects the hardware hierarchy in the system.
// Therefore, the device path may contain intermediate directories (devices).
// Thus, we can not simply find the device path from the PCIAddress.
// Fortunately, /sys/bus/pci/devices/<address> is a symlink to the actual device path in /sys/devices.
// So we can resolve the actual device path by reading the symlink at /sys/bus/pci/devices/<address>.
