Why twice?

Why the extra blank line?
When learning to do kernel changes, I recommend doing so in
drivers/staging/ first, as that is what it is there for. Only after
getting experience would I recommend doing this in other areas of the
kernel, and even then, only do checkpatch cleanups for code that you can
test, or that the subsystem maintainer has explicitly asked for.
good luck!
