Richard Purdie 4a6a1a8c3c kernel-devsrc: Clean up whitespace 
This file had a function full of mixed tabs and spaces. Our policy says
tabs, some layers use spaces but this function matched nothing.

It makes sense to clean this up, I'm torn between which to use. I've gone
with the lesser invasive change (despite what the diff looks like) and used
spaces as the code was clearly written with that partly in mind and tabs would
have changed every line. Hopefully this makes future patches a little less
weird looking.
