I don't know quite what to do about open, close, and ioctl, as those are
quite possibly legit symbols in the kernel's file_operations structures.
However, the puts, printf, and strerror almost certainly should not be
used in the kernel. You have access to printk() for printing debugging
messages, and strerror more or less assumes the presence of an errno
variable. This doesn't hold in the kernel.

add here,
MODULE_LICENSE("GPL");
assuming your module is GPL licensed, of course.
