Who or what is coming up with these ideas and even commenting it?

    // Iterate platform devices
    dir = opendir("/sys/bus/platform/devices/");

    while ((ent = readdir(dir)) != NULL) {

        // Set driver override
        snprintf(path, sizeof(path), "/sys/bus/platform/devices/%s/driver_override", ent->d_name);
        fd = open(path, O_WRONLY);

        // Bind to vhci_hcd
        fd = open("/sys/bus/platform/drivers/vhci_hcd/bind", O_WRONLY);
