protocol_id_show() uses sprintf() to format sysfs output into the page buffer. Convert it to sysfs_emit(), which is the preferred helper for sysfs show() callbacks as it enforces page boundary checks.
Similar conversions have already been made elsewhere in this subsystem (e.g. loopback.c, arche-platform.c).
