Hello, thanks for reviewing this. As of now this is only a warning issue 
in kernel. I saw this post by linus 
https://www.spinics.net/lists/linux-sparse/msg10066.html and thought of 
submitting a patch. Also a similar patch of mine got accepted 
https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg2560740.html, 
so thought about opening this one as well.

Thank You,
Abhinav Singh
