The simple_write_to_buffer() can return success if even a single byte
is copied from user space. In this case it can result in using
uninitalized data if the buf[] array is not fully initialized. Really
we should only succeed if the whole buffer is copied.
Just using copy_from_user() is simpler and more appropriate.
