Andy Whitcroft 543691a6cd tty_register_driver: only allocate tty instances when defined 
If device->num is zero we attempt to kmalloc() zero bytes.  When SLUB is
enabled this returns a null pointer and take that as an allocation failure
and fail the device register.  Check for no devices and avoid the
allocation.
