Subject: RFC : [PATCH] IPV6: checkpatch whitespace corrections

I started looking at the ipv6 code to educate myself but in the process
noticed a fair few trivial checkpatch issues. There are some more interesting
ones also present but before tackling those I decided to try to reduce the 
volume of output from checkpatch by fixing whitespace issues. Question is 
are such patches wanted?

Patch comment:

No actual changes to logic just whitespace adjustments to coding
style as indicated by checkpatch.
