Hi there.
I'm playing kernel module development challenge.
I read http://lxr.free-electrons.com/source/Documentation/CodingStyle and
learn how to write right code.
I am sure that there's no coding style error in following files.
But challenge system say that there are coding style error.
Any hint for me?
Ps: I tried to submit answer without meaningless comment. but It's not
correct.

The challenge system is correct, please do your own work, otherwise,
it's not much of a challenge, is it?
