checkpatch has it's ideas, doesn't mean it's blindly right at all
times. In this particular case it keeps the code more readable to keep
it below 80 characters than it does to add those two blanks and make the
line longer.

I agree the long variable names are nasty, and it doesn't help they were
done in StUdLyCaPs. If you want to attack it from that front, please go
ahead.

However, on formatting, please respond with proper email using proper
quoting when replying.

Thanks,
Jes
