How to submit for eudyptula-challenge

[harry198344@gmail.com (wangyubin)]

Hi, Aruna

Thanks for your answer!

I used printk like this in the previous submit.
printk(KERN_ALERT "Hello World !");

I will change "KERN_ALERT" to "KERN_DEBUG" and try to submit again!

also thanks for Masood Mehmood and Parinay Kondekar's help!

Best Regards!
