For some reason, I was unable to reproduce this in my build with ARM
OMAP5 configuration... but with the x86 configuration, I was.

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/include/linux/module.h#n101

I used MODULE_LICENSE("GPL V2")

Looks like a typo crept in. And s/V/v seems to squelch the warning(at
least in the x86 build) for the randconfig. I will post a patch
accordingly. Thanks for catching the same.
